Question:
Reconsider the previous two exercises about haircut prices. Th e sample mean prices were $21.85 for males and $54.05 for females, a difference of $32.20. Which are appropriate interpretations of the p-value of 0.0022? (Circle all that apply.)
A. There’s a 0.22% chance that women in the population did not pay more on average than males for their most recent haircut.
B. If there were no difference in the population between what females and males paid for their most recent haircut, then there’s a 0.22% chance that the sample mean price for females would have been at least $32.20 higher than the sample mean price for males.
C. If there were no difference in the population between what females and males paid for their most recent haircut, then 0.22% of all random shuffles based on the sample data would produce the shuffled mean price for females being at least $32.20 higher than the shuffled mean price for males.
