A study on the personality characteristics of drug dealers sampled 100 convicted drug dealers and scoredthem each on the Wanting Recognition (WR) Scale, which provides a quantitative measure of a person's needfor approval and sensitivity to social situations. (Higher scores indicate a greater need for approval.) Thesample of drug dealers had a mean WR score of 35, with a standard deviation of 7. Use this information tofind an interval estimate of the mean WR score for all convicted drug dealers. Use a confidence level of 99%.Interpret the result.Construct a 99% confidence interval and interpret the result.(Round to two decimal places as needed.)A. The 99% confidence interval for mean WR score indicates that the true mean WR score for convicteddrug dealers is betweenandwith 99% confidence.B. The 99% confidence interval for mean WR score indicates that 99% of all drug dealers have a WRscore betweenandC. The 99% confidence interval for mean WR score indicates that 99% of convicted drug dealers have aWR score betweenandD. The 99% confidence interval for mean WR score indicates that the true mean WWR score for all drugdealers is betweenandwith 99% confidence.

An experiment was conducted to determine if exposure to an advertisement would change attitude toward a product. Each subject’s attitude before and after exposure to the advertisement was recorded, using a valid ten point scale. The results indicated: Subject Attitude Post Exposure Attitude Pre Exposure 1 6 4 2 8 5 3 6 6 4 4 3 5 7 2 6 6 3 7 9 6 8 7 6 9 8 5 10 8 6 Set up hypotheses and test to determine if the mean attitude toward the product increased as a result of exposure to the advertisement. (Note: these samples must be regarded as dependent, as each subject served as both a control (pre-exposure) and a treatment (post exposure). Fully interpret your result.

I often hear the opinion that "people who listen to classical music are smarter". In an attempt to test that claim, I gave an IQ test to twO groups of people: Group 1: Students who primarily listen to non-classical music. Group 2: Students who primarily listen to classical music.

Consider the following data from mothers divided into four categories according to smoking habits, and the corresponding birthweights of their children. Group 1: Mother is a non smoker (NON): 7.5, 6.2, 6.9, 7.4, 9.2, 8.3, 7.6 Group 2: Mother is an ex-smoker (EX): 5.8, 7.3, 8.2, 7.1, 7.8 Group 3: Mother is a current smoker, smokes less than 1 pack per day (CUR < 1) 5.9, 6.2, 5.8, 4.7, 8.3, 7.2, 6.2 Group 4: Mother is a current smoker, smokes more than or equal to 1 pack per day (Cur ≥ 1) 6.2, 6.8, 5.7, 4.9, 6.2, 7.1, 5.8, 5.4 Using Stata test whether or not the mean birthweights are equal across all four groups at the alpha = 0.05 level.
