Q1. For each of the studies described in questions a) and b), indicate the appropriate statistical test for analyzing the relationship between the variables. Assume that the underlying assumptions of the tests have been satisfied. a) A researcher tested the relationship between college students’ need for achievement as assessed on a 20-item test and their grade point averages. Explain your decision. b) A consumer psychologist studied the relationship between gender and preference for Ford, Chevrolet, and Chrysler cars.

According to the National Health and Nutrition Examination Survey (NHANES) sponsored by the U.S. government, a random sample of 712 males between 20 and 29 years of age and a random sample of 1,001 males over the age of 75 were chosen and the weight of each of the males were recorded (in kg). Do the data provide evidence that the younger male population weighs more (on average) than the older male population? Use “Y” for ages 20-29 and “S” for ages 75+. It was found that x̅Y=83.4, sY=18.7, x̅S=78.5, and sS=19.0. a)Suppose the test statistic is t = 2.398. What is the associated p-value? Group of answer choices 0.001 < p-value < 0.002 0.005 < p-value < 0.01 0.01 < p-value < 0.02 0.0005 < p-value < 0.001 b) Suppose the p-value is 0.02 < p-value < 0.04.
