The school board is trying to evaluate a new math program introduced to second-graders in five elementary schools across the county this year. A sample of the student scores on standardized math tests in each elementary school yielded the following data:

School No. of Test Errors

A.............52

B.............27

C.............35

D.............44

E.............55

Construct a c-chart for test errors, and set the control limits to contain 99.73% of the random variation is test scores. What does the chart tell you? Has the new math program been effective?
