Step-by-step explanation:
We are given the following information in the question:
Percentage of of the diners who make reservations don't show up = 3%
Number of reservations = 83
Thus, we are given a binomial distribution with n = 83 and p = 0.97


Around 81 people can be expected to show up.

The standard deviation of this distribution is 1.56
Since there's 1 hour and 14 minutes until noon, and one hour is 60 minutes, 60 + 14 = 74 minutes until noon.
