Calculate the sample standard deviation for this data set: 58, 60, 74. The formula for the sample standard deviation is shown, where n represents the sample size, x represents each value in the data set, and represents the sample mean. S= (x-x) n-1 Step 1. Calculate the sample mean. Step 2. Calculate the deviations and the squares of the deviations. deviation of 58 = deviation of 60 = deviation of 74 = Step 3. Calculate the sample variance and the sample standard deviation. Provide your sample standard deviation answer precise to one decimal place. sample variance = x = square of deviation of 58 = square of deviation of 60 = square of deviation of 74 = sample standard deviation =
