I've been asked to solve using Excel. Can you please tell me the appropriate functions in excel and briefly explain what is needed with each question? Thank you!

The quality-control manager at a compact fluorescent light bulb (CFL) factory needs to determine whether the mean of life of a large shipment of CFL's is equal to 7,500 hours. The population standard deviation is 1,000. A random sample of 64 CFL's indicates a sample mean life of 7,250 hours.

A)At the 0.05 level of significance, is there evidence that the mean life is different from 7,500 hours?

B)Compute the p-value and interpret its meaning?

C)Construct a 95% confidence interval estimate of the population mean life of the CFL's.

D)Compare the results of (A) and (C). What conclusions do you reach?
