Question

The ordered array below resulted from taking a sample of 20 telephone sales people and finding out how many sales they made in a two-hour period. Sales: 1 1 3 4 5 5 6 6 6 7 8 8 8 9 9 9 10 10 13 18 If the frequency distribution for the sales data is constructed using "l but less than 4" as the first class, that the frequency of the "4 but less than T" class. 4 5 6 If the frequency distribution for the sales data is constructed using -1 but less than 4" as the first class, find the relative frequency of the "10 but less than 13"class. 2 0.90 0.18 0, 10 If the frequency distribution for the sales data is constructed using "1 but less than 4 as the first class the cumulative frequency of the "7 but less than 10" class. 7 16 35 If the frequency distribution for the sales data is constructed using 1 but less than 4" as the first class the cumulative relative frequency of the "7 but less than 10" class. 0.95 0.90 0.80 0.35

Explanation / Answer

Q-2-Option-C as the numbers are “4,5,5,6,6,6”

Q-3-Option-D as the numbers are “10,10” so rel freq=2/20=0.10

Q-4-Option-B as the numbers are all except 10,10,13,18, so cumulative frequency =20-4=16

Q-5-Option-C as the numbers are all except 10,10,13,18, so cumulative relative frequency =1-4/20=0.80
