A researcher is interested in determining if a new intensive treatment program for high school students with alcohol abuse problems is effective. In order to recruit participants for this study, flyers are mailed to all families of high school students in the Northwest Arkansas area. Ninetythree families decide to participate in the study. To test the main research hypothesis, the families are randomly assigned to one of three groups, with the restriction that an equal number of families are in...

Chose the corectt answer(s) questions (1-3) Question 1 Which of the following statements is true? (Select all correct answers) If the mean of two groups remains the same, the P value will not change even if the sample size (n) of those two groups changes. The P value is the probability that the alternative hypothesis is true. In a study of comparing the amount of alcohol consumed by men and women the null hypothesis would be defined as: “There is...

4. Repeated-measures ANOVA Aa Aa Suppose you are interested in studying whether lighting brightness affects spatial reasoning abilities. You decide to test spatial reasoning using completion time scores for the paper-folding test with five people, repeating the test on each person with three different lighting levels (800, 1,000, and 1,200 lux) In this experiment, the null hypothesis is that: O There are no individual differences in the completion time means O The completion time mean for at least one lighting...
