Answer:
27 men had a pulse rate between 56 & 100.
Step-by-step explanation:
We are given the following in the question:
Sample size, n = 36
Five number summary:
Lowest value: 56
Lower Quartile: 71
Median: 80
Upper Quartile: 100
Highest value: 140
We have to find the number of men that had a pulse rate between 56 & 100.
56 is the lowest value of data and 100 is the third quartile of data.
Now, the third quartile give 75 percentile of data, thus, 75% of data lies between lowest value and the third quartile.
Thus, 75% of men have a pulse rate between 56 & 100.
Number of men that had a pulse rate between 56 & 100 =

Thus, 27 men had a pulse rate between 56 & 100.
