Answer (1)
Marginal relative frequency is the number of people who do not like cantaloupe divided by the total number of people.
The number of people who do not like cantaloupe is 91.
The total number of people is 200.
The marginal relative frequency for the people who do not like cantaloupe is 200 91 .
Explanation
Understand the problem and provided data We are given a table that summarizes data about people who like and do not like cantaloupe. The table also provides the totals for each category. We are asked to find the marginal relative frequency for the people who do not like cantaloupe.
Identify the required ratio The marginal relative frequency is the ratio of the number of people who do not like cantaloupe to the total number of people. From the table, we can see that the number of people who do not like cantaloupe is 91, and the total number of people is 200.
Calculate the marginal relative frequency Therefore, the marginal relative frequency for the people who do not like cantaloupe is 200 91 .
State the final answer The marginal relative frequency for the people who do not like cantaloupe is 200 91 .
Examples
Marginal relative frequency is useful in market research. For example, if a company wants to launch a new product, they can survey a sample of people to find out how many people are interested in the product. The marginal relative frequency of people interested in the product can help the company estimate the potential market size.
