A psychologist administers a test of reflex times to men and women. In the study, the reaction speed to an electrical shock stimulus was measured for a sample of men and for a sample of women. The researcher thinks there may be a difference between men and women in this response. Let $\mu$ \mu(M) be the average reaction speed for all men. Let $\mu$ \mu(W) be the average reaction time for all women.

Question

A psychologist administers a test of reflex times to men and women. In the study, the reaction speed to an electrical shock stimulus was measured for a sample of men and for a sample of women. The researcher thinks there may be a difference between men and women in this response. Let $\mu$ \mu(M) be the average reaction speed for all men. Let $\mu$ \mu(W) be the average reaction time for all women.

The appropriate null and alternative hypotheses relevant to this example are

Answer

H_0 : \mu(M) 
eq \mu(W)   and   H_a: \mu(M) = \mu(W)

Answer

H_0 : \mu(M) = \mu(W)   and   H_a: \mu(M) < \mu(W)

Answer

H_0 : \mu(M) = \mu(W)   and   H_a: \mu(M) > \mu(W)

Answer

H_0 : \mu(M) = \mu(W)   and   H_a: \mu(M) 
eq \mu(W)
