Answer:

A. between 38 and 46 waves

Step-by-step explanation:

Step 1: Given data

Hernando estimated about 42 waves give or take 4 waves. That is, the average is 42 waves and 4 waves define the confidence interval.

Step 2: Calculate the minimum number of waves

We have to subtract 4 waves from the average, that is 42 - 4 = 38 waves

Step 3: Calculate the maximum number of waves

We have to add 4 waves to the average, that is 42 + 4 = 46 waves
