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
