The data from Exercise 1.70 (see data set EX0170), reproduced below, show the last digit of the Social Security number for a group of 70 students. 1 6 9 1 5 9 0 2 8 0 7 3 4 2 3 2 0 0 2 1 2 77 4 0 0 9 9 5 3 8 4 6 6 9 0 2 6 2 9 5 1 7 7 7 8 7 4 3 5 8 4 2 8 5 1 3 4 19 3

a. You found in Exercise 1.70 that the distribution of this data was relatively €œflat,€ with each different value from 0 to 9 occurring with nearly equal frequency. Using this fact, what would be your best estimate for the mean of the data set?
b. Use the range approximation to guess the value of s for this set.
c. Use your calculator to find the actual values of xÌ… and s. Compare with your estimates in parts a and b.
