Answer 1

The mean time it takes a computer tech to fix a laptop with a uniform distribution between 15 minutes and 1 hour and 15 minutes (75 minutes) is 45 minutes.

Step-by-step explanation:

To find the mean time it takes a computer tech to fix a laptop when the repair times are uniformly distributed between 15 minutes and 75 minutes (1 hour and 15 minutes), we would use the formula for the mean of a uniform distribution which is (a + b)/2, where 'a' is the minimum value and 'b' is the maximum value. In this case, a is 15 minutes, and b is 75 minutes.

Applying the formula, we have: Mean = (15 + 75) / 2 = 90 / 2 = 45 minutes. Thus, the mean repair time is 45 minutes.
