Use the table to answer the question.
Students Seacoast Mountains Totals
7th Grade 70 40 110
8th Grade 90 110 200
Totals 160 150 310
Determine the relative frequency of the percent of 7th graders who prefer mountains. Round the percentage to the nearest tenth..
To determine the relative frequency of the percent of 7th graders who prefer mountains, we first need to find the total number of 7th graders.
From the table, there are 110 total 7th graders. Of those, 40 prefer mountains.
To find the relative frequency as a percentage, we use the formula:
(relative frequency of 7th graders who prefer mountains) = (number of 7th graders who prefer mountains) / (total number of 7th graders) * 100
Plugging in the values:
(relative frequency of 7th graders who prefer mountains) = 40 / 110 * 100 = 36.4%
Therefore, the relative frequency of the percent of 7th graders who prefer mountains is 36.4%.
