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. Lets say after conducting the study, you get a p-value of 3.432 * 10 ^-5. Do you reject or fail to reject the null hypothesis? If an error was committed, what type would it be?
