Recent polling finds that 71% of the American public supports same-sex marriage, 27% is opposed to same-sex marriage, and 2% are undecided. To see if students at your university have attitudes that mirror the larger U.S. population, you survey 200 students on your campus on their attitudes toward same-sex marriage. To analyze these data, the most appropriate test would be a:

For the data in the source table, what decision can be made about the hypotheses being tested? Source SS df MS F Between-groups 12.1 2 6.05   Subjects 9.8 4 2.45   Error 11.1 8 1.39   Total 33 14      

When the between-groups variance is much larger than the within-groups variance, we infer that the sample means are _____ one another, and we _____ the null hypothesis.

The following table reflects the results of a study by Roediger and Karpicke (2006). The authors investigated whether the test-enhanced learning effect (the demonstration that repeated testing improves memory for material) was due merely to repeated exposure to the material. They randomly assigned participants to one of two study conditions (study–study or study–test) and to one of three retention interval conditions (final test at a delay of 5 minutes, 2 days, or 1 week). The dependent variable was the proportion of idea units recalled from an encyclopedia passage.Table: Test-Enhanced Learning   5 minutes 2 days 1 week Mean Study–study 0.80 0.55 0.42 0.59 Study–test 0.75 0.70 0.55 0.67 Mean 0.78 0.63 0.49     Reference: Ref 14-1 (Table: Test-Enhanced Learning) Based on the cells of this study, which effects appear to be present?

According to guidelines published by Cohen (1988), a correlation value of –0.49 would be considered:

The following figure reflects the results of a hypothetical study examining levels of “Geekiness” in male and female participants who watched either one or five hours of Star Wars related TV shows on the Disney streaming service. Level of “Geekiness” was assessed after viewing with a short questionnaire.Figure: Star Wars programming and Gender Reference: Ref 14-18 (Figure: Star Wars programming and Gender) Based on the figure, which effects appear to be present?
