In each of Exercises, suppose that you want to perform a hypothesis test for a population mean. Assume that the population standard deviation is unknown and that the sample size is relatively small. In each exercise, we have given the distribution shape of the variable under consideration. Decide whether you would use the t- test, the Wilcoxon signedrank test, or neither. Explain your answers.

Expert Solution
Step 1
For testing population mean:
- If sample size is small and the population is normally distributed then t-test can be used.
- If sample size is small and the population is symmetric then Wilcoxon signed rank test can be used.
