Cab you explain or show how they got the number 1540?

\\/ Chapter 2, End of Chapter, CHAPTER EXERCISE, Exercise 38 Part b Part c Part d m Partf Explanation . The cumulative relative frequency is calculated as the sum of the relative frequency of the current class and the relative frequency of the previous class. - The less than cumulative relative frequency is used to compute the number of OS for 75% of Cs. . The relative frequency is the ration between the class frequency and the total frequency. . 16 Relatlve frequency for the rst class : g z 0.67 - The table shows the class, frequency, relative frequency and the less cumulative relative frequency. Classes Frequ Relat Cumulative ency ive relative frequ frequency ency 40 16 0.67 0.67 1040 1040 i 4 0.17 0.67 W 2040 0.17 : 0.84 2040 i 2 0.08 0.84 ~ 3040 0.08 : 0.92 3040 i O O 0.92 W 0 : 4040 0.92 4040 2 0.08 0.92 W 5040 0.08 : 1 . Hence, the 75% of the Cs falls in the class "1040 2040". - Hence, the 75% of the Cs have less than 1540 number of 08. Verified Answer 0 1540
