In a survey, 128 of 200 men said that they suffer from some level of anxiety, while 73 of 150 women said that they suffer from some level of anxiety. Perform a hypothesis test to determine if there is sufficient evidence to conclude that men are more likely to suffer from some level of anxiety than women? Use a 5% level of significance.

1. State the hypotheses

2. Determine α

3. Calculate the test statistic

4. Determine the p-value

5. Make a decision and state the conclusion

Use the two-proportions z-test to perform the required hypothesis test using the P-value approach. Of 85 randomly selected women, 38 have tried some form of alternative medicine. Of 90 randomly selected men, 23 have tried some form of alternative medicine. At the 1% significance level, do the data provide sufficient evidence to conclude that women are more likely than men to try alternative forms of medicine?
