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. Their scores are summarized in the following table : Std. Deviation Group 1 111 98 87 119 108 102 110 10.392 Group 2 100 85 105 97 114 93 9.142 101 < Answer the question using a 0.10 level of significance. Select the correct answer to this question: Which is the approximate value of the Test Statistic for this test? O 7.5344 O -1.1010 O 2.1232 O 1.0923

The mean birthweight of an infant is thought to be associated with the smoking status of the mother during the first trimester of the pregnancy. 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.
