Suppose Professor Alpha and Professor Omega each teach Introductory Biology. You need to decide which professor to take the class from and have just completed your Introductory Statistics course. Records obtained from past students indicate that students in Professor Alpha's class have a mean score of 80% with a standard deviation of 5%, while past students in Professor Omega's Class have a mean score of 80% with a standard deviation of 10%. Decide which instructor to take for Introductory Biology using a statistical argument.
Phyllis, a college business student wants to study how many students in her class study for less than 20 hours per week. Past data reveals that the hours college students study per week has a mean of 29 with standard deviation 9 hours. The normal distribution for the population is shown by the dotted black line. She plans to take a random sample of 36 such college students and will calculate the mean hours studying to compare to the known hours studying. Compute the the mean and standard deviation of the sampling distribution of sample means for a sample of size 36. Round your answers to the nearest tenth. Show your answer by moving the two draggable points to build the sampling distribution.

According to the New York Daily News, March 5, 2014, people 65 years and older watch an average of 50.5 hours of TV per week. We will estimate the standard deviation to be 12.7 hours per week. Your town has many social programs for senior citizens which may reduce the amount of TV that older people watch. You want to find out if it is true that people 65 and older in your town watch less than 50.5 hours of TV per week. So, you sample 40 people 65 and older in your town. You find that the average time that the 40 people watch per week is 45.8 hours. Can the claim be supported to a level of significance of α = .02, test the hypothesis?
