A researcher is wondering whether the smoking habits of young adults (18-25 years of age) in a certain city in the U. S. are different from the proportion of the general population of young adults in the U. S. A recent study stated that the proportion of young adults who reported smoking at least twice a week or more in the last month was 0.16. The researcher collected data from a random sample of 75 adults in the city of interest. Check that the conditions hold so that the sampling distribution of the z-statistic will approximately follow the standard normal distribution. Are the conditions satisfied? If not, choose the condition that is not satisfied.
Select one:
a. No, the researcher did not collect a random sample.
b. No, the population of interest is not large enough to assume independence.
c. No, the researcher did not collect a large enough sample.
d. Yes, all the conditions are satisfied.
