Perform a two-sample z-test for proportions to test if men are more likely than women to make online purchases of books.
The value of the test statistic is:
The p value is:
At the 5% significance level we would (Reject or Fail to?) the null hypothesis and conclude
For a 90% CI for the difference in population proportions, the lower and upper bounds are?
