8. True or False? Test Average and Quiz Average are both significantly correlated with Course %, and they are significantly correlated with each other. Dr. Wright is also interested in whether students who do well on the first test are more likely to do well in the course overall. 9. What statistical analysis should Dr. Wright use to test whether Test 1 was a significant predictor of Course %? A- Spearman CorrelationB- RegressionC- Chi-Square goodness of fitD- Oneway ANOVA Dr. Wright is disappointed, but not surprised. His colleague, Dr. Crea, comes by and reviews Dr. Wright's data and says that maybethis wasn't the right approach. The average of all quizzes couldn't be expected to be highly correlated with individual tests, since eachtest focuses on different material. She says, "Maybe you should see whether the number of quizzes missed is correlated with theoverall course grade or the average test grade. Maybe students who miss more quizzes will have lower grades."Number ofMissedCourse %Test AverageQuiz AverageQuizzes******Course %Pearson Correlation1.788.615-543Sig.
