Answer to relevant QuestionsDetermine the critical values of r for a = 0.05 and n = 20 in the following circumstances: a. Ha is two-tailed. b. Ha is one-tailed. A sample of 20 bivariate data has a linear correlation coefficient of r = 0.43 Does this provide sufficient evidence to reject the null hypothesis that p = 0 in favor of a two-sided alternative? Use a = 0.10. Consider the “Married Couples’ Heights” scatter diagram presented in “Height Compatibility” on page 613: a. Calculate r. b. Set a 95% confidence interval for r. c. Test for a significant positive correlation at the ...The following data values are from a random sample of 40 college students; the data show the students’ gender, American College Test (ACT) composite scores, and grade point averages (GPAs) after their first term in ...State the null hypothesis, Ho, and the alternative hypothesis, Ha, that would be used to test the following statements: a.
