Use the following story to answer questions about hypothesis testing. Let's say we want to study how much screen time the average employee at a particular company is getting in a day. In a sample of 8 employees, they averaged 7.5 hours of screen time with a standard deviation of 45 minutes. (Notice that the standard deviation is in minutes and the average is in hours.) Test the claim that the average screen time is 8 hours. 21. What distribution do you use for the hypothesis test? a. 2 b. T c. Geometric d. Binomial 22. What is the null hypothesis? 3. Ho: u = 7.5 b. Ho: = 8 c. Ho: p #= 7.5 d. Ho: u at 8 e. Ho: p = 8 23. What is the alternate hypothesis? a Hj1=8 b. H;:u<:8 d hjl8 d. ha: p at e. ha:p="#8" let say after conducting the study you get a p-value of a: do reject or fail to null hypothesis a. hypothesis. b. write conclusion about test that has been run. there is enough evidence suggest average amount screen time hours. not c. different from it possible an error was committed when running test. if what type would be i ii>
