Question

1. forty people were asked about their favorite pet. the results are in the following frequency table.

the relative frequencies in the table below were calculated using the row total. complete the rest of the table.

among the girls, what is the relative frequency that liked cats the best?

1. the two - way table shows 50 students that do or do not jog as an exercise and whether they lift weights or not.

the relative frequencies in the table below were calculated using the column total. complete the rest of the table. rounding may be required.

among the joggers, what is the relative frequency that lift weights?

Explanation:

Step1: <Relative Frequency Formula>

The formula for relative frequency (using column total) is \( \text{Relative Frequency}=\frac{\text{Frequency of the category}}{\text{Column Total}}\times100\% \)

Step2: <Identify Values for Joggers who lift weights>

For joggers (column total = 32), the number of joggers who lift weights is 8.

Step3: <Calculate Relative Frequency>

Substitute into the formula: \( \frac{8}{32}\times 100\% \)
