A rаndоm sаmple оf 25 stаtistics examinatiоns was taken. The average score in the sample was 76 with a variance of 144. Assuming the scores are normally distributed, the 99% confidence interval for the population average examination score is _____________. (Z value is 2.576.)Refer to the following formula.σx = σnz = x-μσxStandard Error = σnMargin of Error = zα/2 * σnConfidence Interval = x ± zα/2*σn
