Problem 4 [9 points]: Consider the following two samples: Sample 1: 10, 9, 8, 7, 8, 6, 10, 6, 10 Sample 2: 10, 6, 10, 6. 8. 10. 8, 6, 10 (a) [3 points] Calculate the sample range for both samples. Based on the reths, would you conclude that both samples exhibit the same variability? (b) [3 points] Calculate the sample standard deviations for both samples. Do these quantities indicate that both samples have the same variability? {cl [3 points] Write a short statement contrasting the sample range versus the sample standard deviation as a measure of variability
