It is believed that the average weight of eastern gray squirrels is approximately 17.5 ounces. Supposed that after seeing many eastern gray squirrels in the local area that seem very large, a researcher wonders if the eastern gray squirrels are larger in the local area.

A. Define the parameter, and write the null hypothesis, alternative hypothesis for hypothesis testing for this situation

B. Suppose that the researcher selects squirrels from random locations in the local area and records the following weights (in ounces)

19.4 17.3 18.2 18.6 16.3 17.8 17.8 18.3 16.9

Assuming all the necessary conditions are satisfied, perform the hypothesis test and compute the P-value. (To show your work: Write down which calculator/programs your are using and what values you are entering into the calculator)

C. Does the part b answer provide strong evidence that the eastern gray squirrels in the local area are larger than 17.5 ounces? Briefly explain how you know.
