A professor in the education department believes that a sample of students study less hours per week when compared to the general population of university students. The general population of university students studies an average of 15 hours a week with a standard deviation of 2. The professor randomly samples 16 students and discovers her sample has a mean of 12. Use an alpha level of 0.05 to determine whether these students study less hours per week when compared to the general population.

An economics professor is interested in seeing if the mean hours worked by students in a week at part time or full time jobs (including work study) is greater than 10. To accomplish this, the professor randomly selected 240 students from the university. It was found that the distribution was right skewed and unimodal. The mean was 8 hours with a standard deviation of 4. The professor then did a hypothesis test. Please find the test statistic for this hypothesis...
