Answer to Question 1

r = 0.207

Answer to Question 2

A 90 confidence interval for the population mean would be narrower than that of a 95 confidence interval for the population mean since the t-score for a 90 confidence interval with v = 9 (1.833 ) is smaller than the t-score for the 95 confidence interval in the previous question (2.262 ).
