A sleep researcher performs a study to determine if sleeping in a cool room improves sleep quality in women and randomly assigns a total of 50 women to a cool room condition (n=25) or a normal room temperature condition (n=25).Women in both groups sleep in these conditions and their sleep quality is measured via actigraphy. What condition would you assess in order to perform the appropriate statistical test for this experiment?

A.Is the sample randomly selected?

B.Do the groups have similar standard deviations?

C.Are the sleep quality values normally distributed in each condition?

D.Does the relationship appear linear?
