Question

Consider the following data representing the price of plasma televisions (in dollars). Fill in the graph

1162, 1221, 1204, 1356, 1252, 1240, 1254, 1253, 1192, 1399, 1209, 1361, 1319, 1233, 1136, 1275, 1371,1174, 1403, 1181, 1407

Price of Plasma Televisions (in Dollars)

Class	Frequency	Class Boundaries	Midpoint	Relative Frequency	Cumulative Frequency
1126–1175
1176–1225
1226–1275
1276–1325
1326–1375
1376–1425

Step 1 of 3:  Determine the class width of the classes listed in the frequency table.

Step 2 of 3: Determine the frequency for each class

Step 3 of 3:  Determine the lower class boundary each class

Answer 1

Class	Frequency	Class Boundaries	Midpoint	Relative Frequency	Cumulative Frequency
1126–1175	3	1125.5-1175.5	1150.5	0.1428	3
1176–1225	5	1175.5-1225.5	1200.5	0.2381	8
1226–1275	6	1225.5-1275.5	1250.5	0.2857	14
1276–1325	1	1275.5-1325.5	1300.5	0.0476	`15
1326–1375	3	1325.5-1375.5	1350.5	0.1429	18
1376–1425	3	1375.5-1425.5	1400.5	0.1429	21

Step 1 of 3:  Determine the class width of the classes listed in the frequency table.

1175.5-1125.5 = 50

Step 2 of 3: Determine the frequency for each class

3,5,6,1,3,3

Step 3 of 3:  Determine the lower class boundary each class

1125.5, 1175.5,1225.5,1275.5,1325.5 and 1375.5
