Consider Exercise 9.S.18. The romantic partners of the 36 men discussed in Exercise 9.S.18 were also tested, in the same manner as the men (i.e., they were blindfolded and asked to identify their partner by touching the backs of the hands of three men, one of whom was their partner). Among the women, 25 were successful and II were not. Are these data significant evidence for the hypothesis that men and women differ in their ability to identify their partners?
Consider an appropriate test that uses a non-directional alternative.
Here is computer output for a chi-square test.
X-squared = 4.59, df = 1, p-value = 0.03219
(a) State the null and appropriate directional alternative hypotheses in context.
(b) Compute the sample proportions and the expected frequencies.
(c) If α = 0.05, what is your conclusion regarding H0?
