2x + 5 =7
Subtracting 5 from both sides
= 2x +5-5 = 7-5
=2x = 2
= x = 2/2

Pulse rates (in beats per minute) were collected on a sample of 36 men. The five number summary for the data is as follows: Lo:

algol13

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 =

$75\% \times n\\\\=\dfrac{75}{100}\times 36 = 27$

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