A researcher is wondering whether the drinking habits of adults in a certain region of a country are different than those in the general adult population. Suppose a recent study states that the proportion of adults in the general population who reported drinking once a week or less in the last month is 0.26. The null hypothesis for this test is p = 0.26 and the alternative hypothesis isp # 0.26. The researcher collected data from 150 surveys he handed out at a busy park located in the region. Are the conditions for proceeding with a one-proportion z-test satisfied? If not, which condition is not satisfied? O a. Conditions are not satisfied; the researcher did not collect a random sample. O b. Conditions are not satisfied; the population of interest is not large enough assume independence. O c. Conditions are not satisfied; the sample size is not large enough. O d. All conditions are satisfied.
