D. She should have divided 45 by 82: 55%

Answer :

Sharon should have divided 57 by 152 to calculate the marginal relative frequency for "Traveling out of state" correctly, resulting in approximately 37.5%. Option A

To calculate the marginal relative frequency for traveling out of state correctly, Sharon should have divided the number of families who chose "Traveling out of state" by the total number of families in the sample, not by the column total for "Traveling out of state" alone.

In the given table, the total number of families in the sample is given as 152 in the "Column totals" row. To find the correct marginal relative frequency for "Traveling out of state," Sharon should divide the number of families who chose "Traveling out of state" (which is 57) by the total number of families in the sample (which is 152).

So, the correct calculation would be:

Marginal Relative Frequency = Number of families choosing "Traveling out of state" / Total number of families in the sample

= 57 / 152

≈ 0.375

Converting to a percentage, the correct answer would be approximately 37.5%.

Option A
