Question

1. Fill in the empty cells in the following table (1 pt each; 5 pts total):

Income level	Frequency	proportion	C%
<34,999		.68
35,000 – 99,999		.28
>100,000	10	.04

Answer 1

Proportion 0.04 corresponds to Frequency = 10

So,

Proportion 0.68 corresponds to Frequency = (10/0.04) X 0.68 = 170

Proportion 0.28 corresponds to Frequency = (10/0.04) X 0.28 = 70

Thus, Total Frequency = 170+70 + 10 = 250

Thus, the Table is filled up as follows:

Income level	Frequency	Proportion	C%
<34,999	(10/0.04) X 0.68 = 170	0.68	0.68 X 100 = 68%
35,000 - 99,999	(10/0.04) X 0.28 = 70	0.28	(0.68 + 0.28) X 100 = 96%
>100,000	10	0.04	(0.96 + 0.04) X 100 = 100%

Thus,

Answer is:

Thus, the Table is filled up as follows:

Income level	Frequency	Proportion	C%
<34,999	170	0.68	68%
35,000 - 99,999	70	0.28	96%
>100,000	10	0.04	100%
