Question

Calculate the difference in the proportion of males and the proportion of females that smoke. Give your answer to 2 decimal places

Answer 1

The difference in the proportion of males and the proportion of females that smoke is 0.08

Missing information

In a sample of 61 males, 15 smoke, while in a sample of 48 females, 8 smoke.

How to determine the proportion difference?

The given parameters are:

                             Male           Female

Sample                  61                  48

Smokers               15                   8

The proportion is calculated using:

p = Smoker/Sample

So, we have:

Male = 15/61 = 0.25

Female = 8/48 = 0.17

The difference is then calculated as:

Difference = 0.25 - 0.17

Evaluate

Difference = 0.08

Hence, the difference in the proportion of males and the proportion of females that smoke is 0.08
