the accompanying table gives the number of copies sold for 30 top - selling novels. use data given in the table to construct a frequency distribution with a first class (in millions) of 0 - 99.
copies sold (millions)
500 85 65
300 81 60
300 80 60
200 80 55
140 79 55
140 75 50
120 75 45
100 70 40

85 70 30
construct a frequency distribution.
copies sold (millions) number of books
0 - 99
□ - □
□ - □
□ - □
□ - □
□ - □

Explanation:

Step1: Identify class width

First class is 0-99, so width = 99 - 0 = 99. Next classes: 100-199, 200-299, 300-399, 400-499, 500-599.

Step2: Count frequencies for 0-99

Values: 30,40,40,45,50,55,55,60,60,65,70,70,70,75,75,79,80,80,81,85,85 → 21.

Step3: Count frequencies for 100-199

Values: 100,100,120,140,140 → 5.

Step4: Count frequencies for 200-299

Value: 200 → 1.

Step5: Count frequencies for 300-399

Values: 300,300 → 2.

Step6: Count frequencies for 400-499

No values → 0.

Step7: Count frequencies for 500-599

Value:500 →1.

Answer:

Copies Sold (millions)	Number of Books
100-199	5
200-299	1
300-399	2
400-499	0
500-599	1
