HI how do you solve (b) From public records, individuals were identified as having been charged with drunken driving not less than 6 months or more than 12 months fromthe starting date of the study. Two random samples from this group were studied. In the first sample of 27 individuals, the respondents wereasked in a face-to-face interview if they had been charged with drunken driving in the last 12 months. Of these 27 people interviewed face to face,16 answered the question accurately. The second random sample consisted of 50 people who had been charged with drunken driving. During atelephone interview, 30 of these responded accurately to the question asking if they had been charged with drunken driving during the past 12months. Assume the samples are representative of all people recently charged with drunken driving.(a) Categorize the problem below according to parameter being estimated, proportion p, mean u, difference of means H1 - H2, ordifference of proportions p, - P2. Then solve the problem.O P1 - P2O H1 - H2O P(b) Let p, represent the population proportion of all people with recent charges of drunken driving who respond accurately to a face-to-face interview asking if they have been charged with drunken driving during the past 12 months. Let p2 represent the populationproportion of all people who respond accurately to the question when it is asked in a telephone interview. Find a 90% confidence intervalfor P1 - P2: (Use 3 decimal places.)lower limitupper limit
