The z score for the mean is always 0.
Mean = 0 SD = 1 The whole point of converting to a Z-score is that you have a Standard Normal distribution ie a N(0, 1) distribution.

To find the lowest possible score Alicia could have earned on one test, we can set up an equation. Since her average score is 88 points for all five tests, the total points she earned on all five tests is 5 * 88 = 440 points. If we assume the lowest score on one test is x, then the total points earned on the other four tests would be 440 - x. Since the score range for each test is 0 to 100 points, the lowest possible score Alicia could have earned on one test is 0 points.
