Number of students | لما Ages 15-18 19-22 23-26 27-30 31-34 35-38 اليا | دما به 7 9 Based on the frequency distribution above, find the relative frequency for the class with lower class limit 15 Relative Frequency = % Give your answer as a percent, rounded to one decimal place Submit Question

Answer 1

Solution:
we need to calculate Relative frequency for the class with lower class limit 15 so the class is 15-18, which can be calculated as
Relative frequency for the class 15-18 = Number of students with Ages 15-18/Total number of students = 6/(6+3+3+3+7+9) = 6/31 = 0.1935
So there is 19.4% probability for the class with lower class limit 15.
