herbal supplements

A study at UCLA found that 55% of 100 cosmetic surgery patients take herbal supplements while only 24% of a similar group of 100 people not undergoing surgery take herbal supplements. The researchers needed to determine whether the difference in these two proportions is statistically significant.

a. Would you have chosen to do a one-sided or a two-sided test of significance? Explain your reasons.

b. Are the conditions for inference met?

c. Using the test you chose in part a, find the P-value for a significance test of the difference in the two proportions.

d. Interpret the P-value you found in part c in the context of this situation.
