Show your work - partial credit awarded for incorrect answers. 1) The average number of times a dog has an "accident' while in the house is 5 times per month (the control mean). A veterinary pharmaceutical company has developed a new drug that they believe will reduce the average number of times that a dog has an "accident" while in the house. We wish to test whether a dog who has received the drug has an accident rate that differs from 5 times per month. We are going to conduct a study with 100 dogs and set up the hypothesis at =.05 a) State the null hypothesis, the alternate hypothesis, and the rejection region b) After we conduct the experiment we get a sample mean x = 4.8 accidents per month and s=1. Conduct the test and interpret the result. c) Calculate the p-value for this experiment and interpret the result. d) A different drug, treatment B, is developed and administered. 100 Dogs are given each and the sample mean x = 4.8 and s = 1 for treatment A. The sample mean x = 4.5 and s = 1.2 for treatment B. We want to test if there is a difference. What is the null hypothesis, the alternate hypothesis, and the rejection region? e) Test the hypothesis that treatment B differs from treatment A and interpret the result.
