Answer:
A.) 5 employees
D.) 9 miles or less
Step-by-step explanation:
Frequent Flier Miles(000) ____ Frequency
0 up to 3 __________________ 5
3 up to 6 __________________ 12
6 up to 9 __________________ 23
9 up to 12 __________________ 8
12 up to 15 _________________ 2
Total ______________ 50
Required:
a. How many employees accumulated less than 3,000 miles?
5 employees (from the frequency table)
b. Convert the frequency distribution to a cumulative frequency distribution.
Frequent Flier Miles(000) ____ F ____ cumm/F
0 up to 3 __________________ 5 ____ 5
3 up to 6 __________________ 12 ___ 17
6 up to 9 __________________ 23 __ 40
9 up to 12 __________________ 8 __ 48
12 up to 15 _________________ 2 __ 50
c. Portray the cumulative distribution in the form of a cumulative frequency polygon.
d. Based on the cumulative frequency polygon, about 75 percent of the employees accumulated how many miles or less?
75% of employees
(75 / 100) * total number of employees
0.75 * 50
= 37.5
From the Cummulative frequency polygon, 75% of the employees accumulated about 9 miles or less
