The following is data from a sample: 115, 128, 144, 142, 134, 110, 123, 118, 120, 106 ind the sample variance and sample tandard deviation. Step One: Find the sample size, n, and then ind the sample mean, x. n= X = Step Two: Fill in the table below and find he sample variance, $2. (Note: You do not leed to show your work. Only enter the final :alculation for each step. If you are using a :alculator, be sure to put parenthesis around legative values to show that the entire value $ squared. Example (-2)2 = 4, rather than 22 = - 4). Raw data, x X - X (x - X)2 115 128
