The following is data from a sample: (115, 128, 144, 142, 134, 110, 123, 118, 120, 106} Find the sample variance and sample standard deviation. Step One: Find the sample size, 72, and then find the sample mean, z. T= Step Two: Fill in the table below and find the sample variance, s2. (Note: You do not need to show your work. Only enter the final calculation for each step. If you are using a calculator, be sure to put parenthesis around negative values to show that the entire value is squared. Example (-2)2 = 4, rather than -22= -4).
