Altruism in prairie dogs. Is altruistic behavior influenced by its potential cost? Prairie dogs are social rodents who wam each other of a predator's presence with barking calls. A researcher examined whether close proximity to a predator results in less frequent alam calls because the callers bear more personal risk. The "predator," a stuffed badger controlled remotely, was placed multiple times randomly either near or far from a prairie dog colony. The number of waming calls made by isolated foraging colony members is displayed in the following table: Distance to Predator Near Far 55 78 Alert Cal 29 No Call 80 a) Do the data support the researcher's hypothesis? Null Hypothesis Altemative Hypothesis b) Obtain the test statistic and the P-value. P-Value

The National Highway Association is studying the relationship between thenumberof bidders on a highway project and the winning (lowest) bid for the project. Ofparticular interest is whether the number of bidders increases or decreases the amountof the winning bid.
Dave Fletcher, the general manager of North Carolina Engineering Corporation (NCEC), thinks that his firm’s engineer-ing services contracted to highway construction firms are directly related to the volume of highway construction business contractedwith companies in his geographic area. He wonders if this is reallyso, and if it is, can this information help him plan his operationsbetter by forecasting the quantity of his engineering servicesrequired by construction firms in each quarter of the year? Thefollowing table presents the sales of his services and total amountsof contracts for highway construction over the past eight quarters: a) Using this data, develop a regression equation for predictingthe level of demand of NCEC’s services. b) Determine the coefficient of correlation and the standard errorof the estimate.
The vintage Restaurant is located on Captiva Island, a resort community located near Fort Meyers, Florida. The restaurant, which is owned and operated by Karen Payne, has just completed its third year of operation. During this time, Karen sought to establish a reputation for the restaurant as a high-quality dining establishment that specializes in fresh seafood. The efforts made by Karen and her staff have proved successful, and her restaurant has become one of the best and fastest-growing restaurants on the island. Karen has just concluded that to plan better for the growth of the restaurant in the future, it is necessary to develop a system that will enable her to forecast food and beverage sales by the month for up to 1 year in advance. Karen has the following data available on the total food and beverage sales that were realized during the previous 3 years of operation.

A municipal solid-waste site for a city must be located at Site A or Site B. After sorting, some of the solid refuse will be transported to an electric powerplant where it will be used as fuel. Data for the hauling of refuse from each site to the power plant are shown in Table P2-4. If the power plant will pay $8.00 per cubic yard of sorted solid waste delivered to the plant, where should the solid-waste site be located? Use the city’s viewpoint and assume that 200,000 cubic yards of refuse will be hauled to the plant for one year only. One site must be selected.

Ross White recently opened a landscaping division , that advises home owners and businesses on landscaping and lawn maintenance. The operations manager, Ms. Priya Johnson, is trying to determine the amount of fertilizer that should be applied to a particular lawn in a residential area in San Juan. Ms. Johnson’s analysis has determined that the lawn needs at least 60kg of Nitrogen, 24kg of Phosphorous compounds and 40kg of Potassium compounds for the current season. After checking nearby home and garden centres, Ms. Johnson has found that one of the suppliers is currently having a sale on packaged fertilizer. One type on sale called Xynis, is a 20-5-20 mixture, containing 20% Nitrogen, 5% phosphorous compounds and 20% potassium compounds. It sells at $4 for a 20kg bag. The other type called Yield-all is a 10-10-5 mixture (10% Nitrogen, 10% phosphorous compounds and 5% potassium compounds) selling for $5 for a 40kg bag. Ms. Johnson would like to know how many bags of each type she…
) Consider the following figures showing the situation of the Australian labourmarket in 2018 (figures are per thousand and in percentage).Employed persons ('000) 12 620.7Unemployed persons ('000) 711.9Unemployment rate (%) 5.4Participation rate (%) 65.6a. What is the labour force participation rate? Briefly checking some online sources is it lower or higherthan in other countries? Try to provide some explanation for the difference.b. Assume that the participation rate in Australia changes to 63%, but the adult population and the numberof employed remain unchanged (hint: if the adult population is not reported, you can calculate it easilyfrom the labour force and participation rate). What would be the labour force, the number ofunemployed, and the unemployment rate?c. Go to the latest LFS by the ABS at: www.abs.gov.au/ausstats/abs@.nsf/mf/6202.0.
