Find the relative frequency for the class with lower class limit
15
Relative Frequency = %
Give your answer as a percent, rounded to two decimal places
Solutions
Expert Solution
Total frequency = 6 + 7 + 9 + 6 + 8 + 8 = 44
relative frequency for the class with lower class limit 15 = relative frequency for the class 15-18 = 6/44 = 0.1364 = 13.64%
