Answer 2

Option: D is the correct answer.

D) 0.14

Explanation:

Marginal Relative frequency helps when analyzing a two-way table for research.

It is the ratio of the sum of joint relative frequency in a row or column and a total number of data value.

The number of people who prefer sightseeing=36.

Also total number of people who were surveyed=260.

Hence, the marginal relative frequency of the people who prefer sightseeing is:

36/260=0.138

which is approximately equal to 0.14.

Hence, marginal relative frequency of customers who prefer sightseeing vacations is:

D) 0.14
