Transcribed Image Text:Exhibit 8-12
In order to estimate the average time spent on an exam at a local university, data were collected from a sample of 36
business students over a one-week period. Assume the population standard deviation is 6 hours.
Refer to Exhibit 8-12. With a 95 probability, the margin of error is approximately

Introduction
Margin of error explain the error in the data set. It determine by the combined value of standard error and the critical value. Standard error is calculated using the population standard deviation and the sample size. Thus, the margin of error is defined as :
