Question

the table below shows the favorite movie theater snack for adults and children.

	popcorn	candy	hot dogs	total
children	15	8	2	25
total	35	10	5	50

what is the marginal relative frequency of people that like to eat popcorn?
2/5
3/10
7/10
1/5

Explanation:

Step1: Recall marginal relative frequency formula

Marginal relative frequency = $\frac{\text{Row/Column Total}}{\text{Grand Total}}$

Step2: Identify relevant values

The total number of people who like popcorn is 35 (from the table), and the grand - total number of people surveyed is 50.

Step3: Calculate marginal relative frequency

Marginal relative frequency of people who like popcorn = $\frac{35}{50}=\frac{7}{10}$

Answer:

$\frac{7}{10}$
