6. Consider the two samples shown below: Sample 1: 10 Sample 2: (a) Calculate the sample range for both samples. Would you conclude that both samples exhibit the same variability? Explain. (b) Calculate the sample standard deviations for both samples. Do these quantities indicate that both samples have the same variability? Explain. (c) Write a short statement contrasting the sample range versus the sample standard deviation as a measure of variability. 9 8 7 8 6 10 6 10 10 8 10 8. 6
