Question

A sports club has 84 members who learned baseball, and 42 of those members also learned basketball. There are 25 students who did not learn baseball but learned basketball, and 8 students did not learn either baseball or basketball. Which table best shows the relative frequency of rows for the data?

Answer 1

C. C is the answer to your question.

Answer 2

The relative frequency of rows for the data is

Learn baseball Do not learn baseball Total

Learn basketball 0.63 0.37 1

Do not learn basketball 0.84 0.16 1

Total 0.72 0.28 1

Explanation:

Given information:

Members who learned baseball = 84

Members who learned baseball and basketball = 42

Students who did not learn baseball but learned basketball =25

Students did not learn either baseball or basketball = 8

Using the above information draw a frequency table as shown below:

Learn baseball Do not learn baseball Total

Learn basketball 42 25 67

Do not learn basketball 42 8 50

Total 84 33 117

To find the relative frequency for the data, we divide each element of by the total observations, i.e., 117.

But, to find the relative frequency of rows for the data, divide each element of row by the total of rows.

The relative frequency of rows for the data is

Learn baseball Do not learn baseball Total

Learn basketball
`(42)/(67)\approx 0.63`
`(25)/(67)\approx 0.37` 1

Do not learn basketball
`(42)/(50)=0.84`
`(8)/(50)=0.16` 1

Total
`(84)/(117)\approx 0.72`
`(33)/(117)\approx 0.28` 1
