A researcher is wondering whetherthe drinking habits of adults in a certain regionof the country are in the same proportion as thegeneral population of adults. Suppose a recentstudy stated that the proportion of adults whoreported drinking once a week or less in the lastmonth was 0.26. The null hypothesis for thistest is Ho: p = 0.26 and the alternativehypothesis is Hap<0.26. The researchercollected data from 150 surveys he handed outat a busy park located in the region.To continue the study into the drinking habits ofadults, the researcher decides to collect datafrom adults working in "white collar" jobs to seewhether their drinking habits are in the sameproportion as the general public. The nullhypothesis for this test is Ho: p = 0.26 and thealternative hypothesis is Ha: p<0.26. Theresearcher collected data from a random sampleof 120 adults with "white collar" jobs of which25 stated that they drank once a week or less inthe last month. Assume that the conditions thatmust be met in order for us to use the N(0, 1)distribution as the sampling distribution aresatisfied. Find the values of the sampleAproportion, p, the test statistic, and the p-valueassociated with the test statistic. Round all
