Find the mean: Find the median: Find the range: Find the variance: time to solve Rubik's Cube 67 63 75 Find the standard deviation: 64 66 57 59 62 (seconds)^2 60 70 58 68 74 71 55

This problem will walk you through the steps to find the sample standard deviation for the following data set which represents a sample taken from a larger population. X 12 13 29 15 27 Step 1. Compute the sample mean of the data. Step 2. Compute the squared deviations from the mean. (x - 2)² x 12 13 29 15 27 Step 3. Now compute the sample variance s² = Σ(z - #) n-1 The formula for s2 is telling you to sum (add up) the squared deviations that you just computed, and then divide by n 1, where n denotes the sample size (the number of values).

Step 2. Compute the squared deviations from the mean. I 12 13 29 15 27 Step 3. Now compute the sample variance s² = Σ(x - 2)² n-1 The formula for s² is telling you to sum (add up) the squared deviations that you just computed, and then divide by n 1, where n denotes the sample size (the number of values). - Step 4. Now compute the sample standard deviation s = 8= Σ(z - #) n-1 This is the square root of the value s² you just computed. Write your answer to at least 2 decimal places.
