Consider the following sample data. Sample A: 3, 7, 11 Sample B: 74, 78, 82 Sample C: 1,065; 1,069; 1,073 (a) Find the mean and standard deviation for each sample. Sample A Sample B Sample C Mean 1.069 Sample Standard Deviation (b) What does this exercise show about the standard deviation? O The idea is to illustrate that the standard deviation is not a function of the value of the mean. The idea is to illustrate that the standard deviation is a function of the value of the mean
