What can be concluded at the a = 0.01 level of significance?
For this study, we should use z-test for the difference between two population proportions
a. The null and alternative hypotheses would be:
Ho: P1
p2
V (please enter a decimal and
note that p1 and ul represent the proportion and mean for women and p2 and µ2 represent the
proportion and mean for men.)
H: p1
Vv (Please enter a decimal)
b. The test statistic z v-
