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.
