Explanation Given: The mean x ¯ = 50 and the standard deviation s = 6 . Calculation: The mean x ¯ = 50 and the standard deviation s = 6 . So, the value of k for the number less than 38 or more than 62, x ¯ − k × s = 38 50 − 6 k = 38 6 k = 12 k = 2 Therefore, the number 38 is 2 standard deviation below the mean 50, and the number 38 is 2 standard deviation above the mean 50
