Question

Use the relative frequency histogram below to complete each part Identify the class with the greatest and the class with the least frequency. Approximate the greatest and least relative frequencies. Approximate the relative frequency of the second class. Emergency Response Time What are the boundaries of the class with the least relative 2-3% 22 - 23 minutes 21.5-22.5 minutes 21-22 minutes What is the greatest relative frequency? (Round to the nearest integer as needed) What is the least relative frequency? (Round to the nearest integer as needed) What is the relative frequency of the second class?

Explanation / Answer

Question 1:

Highest Frequency is 40 the corresponding class = 20 - 21

Least frequency is 2 the corresponding class = 22 - 23

Question 2: Relative Frequency = sub group count / Total count

Total count = 19 + 35 + 40 +8 +2 =104

Least relative frequency = 2 / 104 = 0.0192 = 1.92% = 2 ( Round )

Greates relative frequency = 40 / 104 = 0.3846 = 38.46% = 39 ( Round)

Question (3)

Second class Relative frequency = 35 / 104 = 0.3365 = 33.65% = 34 (round)
