Quizplus · Accepted Answer

To find the missing value, X, first calculate the sum of the given numbers excluding X, then use the average formula to solve for X. The sum of the given numbers is 751. Since the average is 60.31 and there are 13 data values, the total sum should be 60.31 * 13 = 784.03. Subtracting the sum of the known values from this total gives X = 784.03 - 751 = 33.
