Expert Solution
Step 1- Writing given data

Given that 

Randomly selected males (n) = 153 

The pulse rates vary from 

Low = 37 bpm

High = 101 bpm

Confidence level (C) = 98% 

The sample mean is within 4bpm of the population mean.

Margin of error (E) = 4

We know that 

For 98% confidence level z critical value is 2.326

Zc = 2.326
