1 Make a contingency table a Using the Mar Per Start and Mar

1. Make a contingency table: a) Using the Mar Per Start and Mar Per End sale amounts Alternating Between 40% and 50% of total years sales from the given original data tables, B) rows=types, columns=times

Time of the school year

types of study guide

amount of sales

Mar per 1 start = MarPer 1a

Angles

1,000

Mar per 1 end = MarPer 1b

Proofs

3,000

Mar per 2 start = MarPer 2a

Triangle

1,000

Mar per 2 end= MarPer 2b

Mar per 3 start = MarPer 3a

Mar per 3 end = MarPer 3b

Mar per 4 start = MarPer 4a

Mar per 4 end = MarPer 4b

Time of the school year	types of study guide	amount of sales
Mar per 1 start = MarPer 1a	Angles	1,000
Mar per 1 end = MarPer 1b	Proofs	3,000
Mar per 2 start = MarPer 2a	Triangle	1,000
Mar per 2 end= MarPer 2b
Mar per 3 start = MarPer 3a
Mar per 3 end = MarPer 3b
Mar per 4 start = MarPer 4a
Mar per 4 end = MarPer 4b

Solution

Following should be the contingency table:

	Time of the school year
Tyoe of study Guides	1a	1b	2a	2b	3a	3b	4a	4b
Angles	400	500	400	500	400	500	400	500
Proofs	1200	1500	1200	1500	1200	1500	1200	1500
Triangle	400	500	400	500	400	500	400	500
