- The manufacturer of hardness testing equipment uses steel-ball indenters to penetrate metal that is being tested. However, the manufacturer thinks it would be better to use a diamond indenter so that all types of metal can be tested. Because of differences between the two types of indenters, it is suspected that the two methods will produce different hardness readings. The metal specimens to be tested are large enough so that two indentions can be made. Therefore, the manufacturer uses both indenters on each specimen and compares the hardness readings. Construct a 95% confidence interval to judge whether the two indenters result in different measurements. Note: A normal probability plot and boxplot of the data indicate that the differences are approximately normally distributed with no outliers. Click the icon to view the data table. Construct a 95% confidence interval to judge whether the two indenters result in different measurements, where the differences are computed…The manufacturer of hardness testing equipment uses steel-ball indenters to penetrate metal that is being tested.

- People come to relationships with different attachment styles that partially stem from the attachments they experienced with the adults raising them and partially due to experiences in other relationships in their lives. Those who have what is known as “secure” attachments are comfortable with their partners emotions, can help soothe, and make movements towards the other person in a responsive way. Among a group of 10 individuals rated as having a secure attachment style, a researcher wanted to know if, as they were first being acquainted with another person, the amount of self-disclosure made them like their person more. The data is listed in Table 6 below. Test the hypothesis at an alpha of 0.05 (where increasing scores mean higher disclosure and higher liking). If you knew the new person you are about to go on a date with had a self-disclosure rating of 4, what would you predict your likeability score would be (provide the full regression formula as well as the response)? -use…People come to relationships with different attachment styles that partially stem from the attachments they experienced with the adults raising them and partially due to experiences in other relationships in their lives.

- A new restaurant with 134 seats is being planned. Studies show that 57% of the customers demand a smoke-free area. How many seats should be in the non-smoking area in order to be very sure (μ+3σ) of having enough seating there?An explosion at a construction site could haveoccurred as the result of static electricity, malfunctioningof equipment, carelessness, or sabotage. Interviews withconstruction engineers analyzing the risks involved ledto the estimates that such an explosion would occur withprobability 0.25 as a result of static electricity, 0.20 as aresult of malfunctioning of equipment, 0.40 as a result ofcarelessness, and 0.75 as a result of sabotage. It is alsofelt that the prior probabilities of the four causes of theexplosion are 0.20, 0.40, 0.25, and 0.15. Based on all thisinformation, what is(a) the most likely cause of the explosion;(b) the least likely cause of the explosion?In a winter with a flu epidemic, a well-known pharmaceutical company studied 2,000 babies to determine if the company's new drug was effective after two days. Among 120 babies who had the flu and were given the drug, 29 were cured within two days. Among 280 babies who had the flu but were not given the drug, 56 were cured within two days. Is there any significant indication to support the company's claim of the drug's effectiveness? Note:The exercise in the image is the original, it is in Spanish, but it is easy to understand.
- A group of medical professionals is considering theconstruction of a private clinic. If the medical de-mand is high (i.e., there is a favorable market for theclinic), the physicians could realize a net profit of$100,000. If the market is not favorable, they couldlose $40,000. Of course, they don’t have to proceedat all, in which case there is no cost. In the absenceof any market data, the best the physicians can guessis that there is a 50–50 chance the clinic will be suc-cessful. Construct a decision tree to help analyze thisproblem. What should the medical professionals do?The KLM Christmas tree Farm owns a plot of land with 5000 evergreen trees.Each year KLM allows retailers of Christmas trees to select and cut trees for sale to individualcustomers. KLM protects small trees (usually less than 4 feet tall) so that they will be availablefor sale in future years. Currently, 1500 trees are classified as protected trees, while theremaining 3500 are available for cutting. However, even though a tree is available for cuttingin a given year, it may not be selected for cutting until future years. Most trees not cut in agiven year live until the next year, but some diseased trees are lost every year. In viewing the KLM Christmas tree operation as a Markov process with yearly periods, we define thefollowing four states:The Collector’s Choice Inc. (CCI), a luxury car import company, has an old warehouse at the Port of Miami, Florida, where it temporarily stores expensive sports cars and automotive parts that arrive from Europe. This summer, CCI has noticed that the termite infestation in the warehouse has escalated to a point where tenting cannot be postponed anymore. (Tenting is the process of wrapping a building inside a huge tent that is subsequently filled with a poisonous gas capable of killing most forms of life inside, including insects, plants, pets, and human beings.) CCI’s pest control company’s contract specifies a to-do list of pre-tenting tasks, which include: Turning off all air-conditioning units and opening all windows of the warehouse Turning off all internal and external lights, including those operating on a timer Pruning all outdoor vegetation at least 18" away from the warehouse Soaking the soil around the warehouse on the first day of tenting The requirement of opening all…
