HELPPPPP!!!! 30 POINTS!!!!

Generate a frequency table for the following data: 3, 12, 25, 2, 3, 6, 17, 17, 15, 13, 20, 12, 21, 18, 19.
Use the ranges listed in the table below:

Range Number of Values Relative Frequency
1 – 5
6 – 10
11 – 15
16 – 20
21 – 25


What is the relative frequency for the range 11 – 15?
a. 0.8
b. 0.03
c. 0.27
d. 3

Answer 1

Relative frequency:

1 - 5: 3 / 15 = 1 / 5 = 0.2

6 - 10: 1 / 15 = 0.07

11 - 15: 4 / 15 = 0.27

16 - 20: 5 / 15 = 1/3 = 0.33

Number of Values: 21 - 25: 2 /15 = 0.13

1 - 5: 3

6 - 10: 1

11 - 15: 4

16 - 20: 5

21 - 25: 2

What is the relative frequency for the range 11 – 15?

C

Explanation:

Number of values:

1 - 5: 3

6 - 10: 1

11 - 15: 4

16 - 20: 5

21 - 25: 2

Relative frequency:

(Relative frequency is going to be the number of values of a given group, divided by total values)

1 - 5: 3 / 15 = 1 / 5 = 0.2

6 - 10: 1 / 15 = 0.07

11 - 15: 4 / 15 = 0.27

16 - 20: 5 / 15 = 1/3 = 0.33

21 - 25: 2 /15 = 0.13

The relative frequency for the range 11 - 15 is 0.27,

or C
