The middle 95% of customers have to wait for 18 to 34 minutes at the resturant.

What is the empirical rule?

The empirical rule states that for a normal distribution. 68% of the values are within one standard deviation from the mean, 95% of the values are within two standard deviation from the mean and 99.7% of the values are within three standard deviation from the mean

Given a mean of 26 minutes and a standard deviation of 4 minutes. Hence:

95% are within 2 standard deviations = 26 ± 2(4) = (18, 34)

The middle 95% of customers have to wait for 18 to 34 minutes at the resturant.
