Students seacoast mountains totals
7th 60, 40, 110
8th 90,110, 200
Totals 160, 150, 310
Determine the relative frequency of the percent of seventh graders, who prefer mountains round the percentage to the nearest 10th
To find the relative frequency of seventh graders who prefer mountains, we will use the formula:
Relative Frequency = (Number of students who prefer mountains in 7th grade) / (Total number of students)
Relative Frequency = 60 / 160 = 0.375
To convert this to a percentage rounded to the nearest tenth, we multiply by 100:
Relative Frequency = 0.375 * 100 = 37.5%
Thus, the relative frequency of seventh graders who prefer mountains rounded to the nearest tenth is 37.5%.
