P≈0.00000000065 . which is clear evidence we should reject the null hypothesis and concluded that the proportion of young men and young women that live with their parents is different)We now want to look at the confidence interval by finding the difference in the sample proportions:

This test statistic is so large that by Table A the P-value is very close to 0 (by calculator, P-value = 0.00014). Conclude: A P -value of 0.00014 is much less than _ = 0.05, so we reject H 0 . We have sufficient evidence to conclude that the proportions of people who experience adverse reactions to acetaminophen and ibuprofen are different.

Comparing Two Proportions. Use the two-sample z procedure to give a confidence interval for the difference between proportions in two populations based on independent SRSs from the populations. Use a two-proportion z test to test the hypothesis that proportions in two distinct populations are equal.
