Instructions: For the following two questions do the following: a. Identify the null and alternative hypotheses and express in symbolic form b. Name the hypothesis test that is appropriate and explain why this is the appropriate test. c. Write out the test statistic formula you would use. Do not enter any numbers or solve. 1. The bus schedule says your trip to school should take 25 minutes. Sometimes it takes a bit longer, sometimes a bit less, but you wonder whether on average it's longer than what the schedule indicates. You timed your ride every day for 30 days and recorded the duration in minutes (data not shown). Test the hypothesis that the bus takes longer than the schedule says it should. 2. Using the following data, and assuming that both populations are normally distributed with unequal variances, test the null hypothesis that the male and female turtles have the same mean serum cholesterol levels. Serum cholesterol (mg/100 ml) levels of turtles are as below. (Remember: only do what is asked in the above instructions!)
