1 point The scatterplot below displays the relationship between grade point average (GPA) versus weekly television time for a group of high school seniors. Notice that the association is negative, and that the points are more spread out for lower numbers of television hours. GPA 10 20 30 Weekly television hours Suppose the variables on the scatterplot were reversed, so that weekly television hours was the response variable on the vertical axis, and GPA was the explanatory variable on the horizontal axis. Which of the following would be true? The direction and strength of the association would not change. o The association would be positive, but the strength would not change. The association would be positive, and the strength would increase. The association would still be negative, but the strength would increase. The association would still be negative, but the strength would decrease. - 1 point The bowling averages for professional bowlers has a mean less than the median. For each of 15 professional bowling leagues, a random sample of 100 members is obtained. For each sample, the mean bowling average is calculated. Which of the following graphs most likely illustrates the distribution of the sample means? 1 200 300 200 300 200 300 The heights of all the players on two high school football teams are measured, and the following parallel boxplots give a comparison of the resulting five-number summaries. l 1 T 1 TTTTTTT T T T T T T T T T T T T T T T T T T 60 65 70 75 Height (inches) Which of the following is a reasonable conclusion? Distribution | is skewed left, while distribution Il is bell-shaped. Distribution | is skewed right, while distribution Il is bell-shaped. The mean of distribution | is less than the mean of distribution I1. The range of distribution | is approximately 73.5 - 67 = 6.5. The percent of values between Q1 and Q3 in distribution | is greater than the percent of values between Q1 and Q3 in distribution 1. 1 point } Research strongly suggests that drinking sugary beverages are a risk factor for developing liver cancer. Because of public information campaigns, a dietician believes that less than 55% of adults drink at least one sugary beverage a day. To test her belief she interviews a random sample of 400 adults. If 192 of them drink at least one sugary beverage a day, what is the resulting P-value? 0.48-0.55 / 0.55-0.45 400 P(Z
