The mean score on a set of 18 tests is 82 What is the sum of all the test scores? The sum of all the test scores is

Step 1 ：The problem provides that the mean score on a set of 18 tests is 82.

Step 2 ：The mean score is calculated by dividing the sum of all scores by the number of scores.

Step 3 ：Therefore, to find the sum of all scores, we can multiply the mean score by the number of scores.

Step 4 ：In this case, we multiply 82 (the mean score) by 18 (the number of tests).

Step 5 ：Performing the calculation, \(82 \times 18 = 1476\).

Step 6 ：Final Answer: The sum of all the test scores is \(\boxed{1476}\).
