In this problem, we explore the effect on the standard deviation of adding the same constant to each data value in a data set. Consider the following data set. 8, 8, 8, 11, 16 (a) Compute the value of s. (Enter your answer to two decimal places.) s= (b) Add 7 to each data value to get the new data set 15, 15, 15, 18, 23. Compute s. (Enter your answer to two decimal places.) s= In this problem, we explore the effect on the standard deviation of multiplying the same constant to each data value in a data set. Consider the following data set. 5, 5, 5, 8, 13 (a) Compute the value of s. (Enter your answer to two decimal places.) s= (b) Multiply 3 to each data value to get the new data set 15, 15, 15, 24, 39. Compute s. (Enter your answer to two decimal places.) s=
