For the following question, type the solutions to each part of the question in the space provided at the bottom of the question. Make sure you label each part of the question very carefully:

A researcher wants to know if the clothes a woman wears is a factor in her GPA. The table below shows data that was collected from a survey.

Jeans	Dress	Skirt	Shorts
3.3	2.6	3.9	2.8
2.5	3.2	2.2	2.8
2.7	3.4	1.9	3.9
3	2.6	3.6	2.5
3.6	3.6	4	3.1
1.9	3.8	2	3.5
2.2	2	3.6	2.4
2.7		2.1
2.5

Assume that all distributions are normal, the four population standard deviations are all the same, and the data was collected independently and randomly. Use a level of significance of α=0.1.

State the null and alternative hypotheses, compute the test statistic, the p-value, and and state the conclusion of the test
