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 A No. of Test Errors 48 21 B 32 D 40 E 52 For the test errors, the c-chart with control limits that contain 99.73% of the random variation in test scores is: UCLC = 57.24 errors (round your response to two decimal places). LCL = errors (round your response to two decimal places and if your answer is negative, enter this value as 0)
