Textbook Question
Chapter 1, Problem 1.16ACB
Jamming attacks on wireless networks. Terrorists often use wireless networks to communicate. To disrupt these communications, the U.S. military uses jamming attacks on the wireless networks. The International Journal of Production Economics (Vol. 172, 2016) described a study of 80 such jamming attacks. The configuration of the wireless network attacked was determined in each case. Configuration consists of network type (WLAN, WSN, or AHN) and number of channels (single- or multi-channel).
- a. Suppose the 80 jamming attacks represent all jamming attacks by the U.S. military over the past several years, and these attacks are the only attacks of interest to the researchers. Do the data associated with these 80 attacks represent a population or a sample? Explain.
- b. The 80 jamming attacks actually represent a sample. Describe the population for which this sample is representative.
- c. Identify the variable "network type" as quantitative or qualitative.
- d. Identify the variable "number of channels" as quantitative or qualitative.
- e. Explain how to measure number of channels quantitatively.

Several Governments in CARICOM nations are reluctant to allow the provision oftelecommunication services by multiple providers. They prefer that a GovernmentAgency provides these services as they believe that consumers will be protected.However the revenue they gain should not be ignored as a possible motive. A recentstudy found that 8 countries out of the 15 in the CARICOM nations’ havetelecommunication services being provided by the a state company. For example, in St.Lucia, De Phone is the sole provider of telecoms. They offer discounts to senior citizensand students and also provide a lower price for individual who purchase multiple plans.Of note, the remaining CARICOM nations, including Trinidad and Tobago, have openedtheir markets to competition. These countries have seen increased advertising amongcompetitors to market their product.i.

COVID-19 has caused several shortages: paper products, hand sanitizer, and even nurses. When a hospital needs nurses, they might call Fastaff, which has been sending its nurses all around the country. Once a nurse gets an assignment, they pack their bags and need to be there within a week. During a pandemic, these assignments come with some risk, but these nurses are well compensated for their time. “They really run into the fire,” explained Fastaff Senior VP of Marketing Lauren Pasquale-Bartlett. “They’re very brave, they’re like the special forces of nursing. They go in for these really critical assignments.” The need for traveling nurses across the country has increased drastically because of the coronavirus pandemic. One of the state’s needing nurses is Ohio, according to Pasquale-Bartlett. “Particularly in the last few weeks we’ve seen a two to three increase in demand in requests for nurses to come in and support the staff,” she said. “That really indicates to us that it’s an…

Consequently, residents of country B want to immigrate to country A. The trouble is that there is no legal way to do. So they attempt to cross the border Illegally. There are 3 border crossings at which a resident of B may attempt to cross the border. An attempt is successful if there is no border guard at the crossing, and unsuccessful if there is a guard at the crossing. Country A has only 1 border guard. Model the game in which a resident of country B attempts to enter country A at one of the 3 border crossings, and the government of country A chooses to post its border guard at one of the 3 border crossings. In this game, each player has 3 pure strategies. A) What are the ultimate outcomes in this game? B) What are the player's Bernoulli Payoffs?

- Business group Business Unity South Africa (BUSA) has written to Transport minister Fikile Mbalula requesting he makes changes to South Africa’s regulations around the transportation of logistics containers. According to BUSA, Regulation 224 (b) of the National Road Traffic Act currently prohibits the transportation of high cube containers on South African roads. “High cube containers constitute the overwhelming majority of containers currently manufactured and transported internationally – including in neighbouring states,” it said. “However, the combined height of a vehicle transporting a high cube container is currently 4.6 metres – 300mm above the legal limit.” Despite several years of industry engaging the Department of Transport on the matter, as well as moratoriums being issued, no progress has yet been forthcoming on fundamentally resolving the issue, the group said. “This regulatory anomaly puts South Africa’s trade and logistics regime out of step with international and…arrow_forwardBusiness group Business Unity South Africa (BUSA) has written to Transport minister Fikile Mbalula requesting he makes changes to South Africa’s regulations around the transportation of logistics containers.

You want to sell a 2005 Honda Civic LX. You know that this car is of high quality, and it cost you $5000 to acquire it (so you will not sell it at a price below $5000). However, consumers cannot see the quality of the car at the time of purchase. They believe that 25% of the cars in the used car market are high-quality cars and 75% are low-quality cars or “lemons.” A typical lemon costs $2000 to acquire (so you will not sell it at a price below $2000). Consumers are eager to buy and are willing to pay up to $3000 for a lemon and $6000 for a high-quality car. From now on, suppose that only you (the seller) know the quality of the cars. (Buyers do not know the quality, but know the proportion of high- and low-quality cars in the market). Suppose that you could offer bumper-to-bumper warranties. You know that offering a warranty on a high-quality car costs, on average, $450 per year of warranty offered, while a warranty on a lemon is very…arrow_forward
- A local manufacturer is in the process of introducing a new product to all of its retailers. The manufacturer has conducted a survey of consumers, as well as performed trial runs with selected retailers, and discovered the following information about demand for the new product at various price levels: Demand for New Product Quantity Demanded(Number of Units) Price per Unit ($) 300 15 250 25 200 35 150 45 100 55 50 65 0 75 The manufacturer has the following information about how many units they are willing to supply to each retailer at various price levels: Supply for New Product Quantity Supplied(Number of Units) Price per Unit ($) 0 7.50 50 22.50 100 37.50 150 52.50 200 67.50 250 82.50 300 97.50 At what quantity and price will both manufacturer and consumer find equilibrium?

Suppose that, for each person watching a video, YouTube receives one dollar in ad revenues (P=1). Arthur is a professional video-game player. He plays the video-game "Fortnite" and uploads his video to YouTube. The number of people who will watch his video depends on Arthur's effort producing the video and increasing its quality. The number Q of viewers as a function of Arthur's effort "e" is given by the function Q= Be. Arthur's offort cost is 202. His utility equals his income minus ys effort cost. To give incentives to Arthur to create better videos and attract more viewers, YouTube decides to pay Arthur a bonus b for each person watching his video. YouTube also has an operational cost 30 Operational cost - 32 which is the cost of maintaining its internet servers and administrative staff.

- Your firm operates in a market of 200,000 people. By your estimates, you need an install base (people that are willing to use your product after trial) of approximately 40,000 people. Historically, you know that 40% of the people that try your product become regular users. After speaking with some advertising executives, they explain that it takes roughly 10 advertisements on local television stations to get 60% of the viewers to try a product they see on television in this market. These same executives have quoted a Cost Per Point (CPP) of $100, where they define a Gross Rating Point as 1% of the population seeing 1 advertisement. 4a) How much will it cost to achieve your objective?arrow_forwardJazmah Industries received a patent on their new ozone generator. The product will sell for $471, and it will clean the air inside a home and eliminate 95% of the pollution particles inside the home. Jazmah's market research shows that there are 111 million homes in North America. The firm believes an aggressive marketing campaign focusing on heavily polluted regions of the country will allow them to get about 30% of this market. Their research shows that about 43% of the houses are in heavily polluted areas. How many houses are in Jazmah's target market? $674, 424,900 $ 6, 744, 249, 000 $4, 242, 275,000 $4, 709, 314, 000 $8, 730, 854, 000arrow_forwardGM’s Food Shops has completed a study of weekly demand for its “new-fashioned” tacos in 53 regional markets.
