Question

when 30 older women were asked about the types of exercise that they most often participate in, the responses were walking(w), biking(b), jogging(j), yoga(y), running(r) and weight training(t). the data for the 30 women is given below.

what percentage of the 30 women engaged in jogging?
17%
23%
27%
30%
37%

Explanation:

Step1: Count the number of 'J' (jogging)

By looking at the data, we count the number of 'J's. There are 7 'J's.

Step2: Calculate the percentage

The formula for percentage is $\frac{\text{Number of joggers}}{\text{Total number of women}}\times100$. So we have $\frac{7}{30}\times100=\frac{700}{30}\approx23.33\%$. Rounding to the nearest whole number gives 23%.

Answer:

23%
