The charge-to-tap time (min) for a carbon steel in one type of open hearth furnace was determined for each heat in a sample of size 46 , resulting in a sample mean time of 382.1 and a sample standard deviation of 31.5. Calculate a 95 % upper confidence bound for true average charge-to-tap time. | Numerade

The charge-to-tap time (in minutes) for a carbon steel in one type of open hearth furnace was determined for each heat in a sample of size 150. The following summary statistics were observed: (a) Calculate a 95% confidence interval for the true average charge-to-tap time.(b) Calculate a 95% upper confidence limit for the true average charge-to-tap time. Explain why this answer is different from the upper limit in part (a). (Do not use an explanation like "because there is a different formula")
