Scenario 8.2
The undergraduate grade point average (GPA) for studentsadmitted to the top graduate business schools was 3.37. Assume thisestimate was based on a sample of 90 students admitted to the topschools. Using past years' data, the population standard deviationcan be assumed known as 0.30. Â
1. Based on the information in Scenario 8.2, you are toconstruct a 95% confidence interval estimate of the meanundergraduate GPA for students admitted to the top graduatebusiness schools, that is
[ Lower limit , Upper limit ].
The Lower limit of this 95% confidenceinterval is equal to ? (to 2 decimals)?
