Q13MSampling and EstimationFree sample

The time taken for a particular type of paint to dry was measured for a sample of 150 randomly chosen points on a wall. The sample mean was 192.4 minutes and an unbiased estimate of the population variance was 43.6 minutes2^2. Find a 98% confidence interval for the mean drying time.
