At α=0.05, can it be shown that the percentage of women who were attacked by relatives is greater than the percentage of men who were attacked by relatives? Use p1 for the proportion of women who were attacked by relatives. Use the critical value method with tables and round all intermediate calculations to at least three decimal places.

(a) State the hypothesis and identify the claim with the correct hypothesis.

H0: ▼(Choose one)

H1: ▼(Choose one)

This hypothesis test is a ▼(Choose one) test.
