A survey of 430 randomly chosen adults found that 21% of the 222 men and 18% of the 208 women had purchased books online. A researcher used a Z Test Difference of Proportions to investigate this observed difference in proportions and calculated p-value 0.22.a. Each of the following conclusions is wrong. Briefly explain why.

I. There is strong evidence that men are more likely than women to purchase books online.

II. Since the p-value is high, we have evidence that there is no difference in the proportions of men and women who buy books online.

III. There is a 22% chance that the same proportion of men and women buy books online.

b. What is a meaningful conclusion for this hypothesis test.
