Problem 1.51 The frequency distribution for the heights of 36 adult males is given in the table below. Key to the table: Height = x and Freq = f(x). HEIGHT 64.9 65 65.5 66 67 67.8 68 68.1 68.5 69 70 FREQ 1 2 1 1 1 1 1 1 1 3 3 HEIGHT 70.1 70.5 70.8 71 71.8 72 72.8 73 73.5 74 75 Freq 1 1 1 6 1 2 1 1 2 2 2 Compute the sample mean and sample standard deviation of the variable height. Hint: Use Equations 1.23 and 1.24.
