The quality-control manager at a light bulb factory needs to determine whether the mean life of a large shipment of light bulbs is equal to 375 hours. The population standard deviation is 100 hours. A random sample of 64 light bulbs indicates a sample mean life of 350 hours.

Required Tasks:

1. At the 0.10 level of significance, is there evidence that the mean life is different from 375 hours?

2. Compute the p-value and interpret its meaning.

3. Construct a 90% confidence interval estimate of the population mean life of the light bulbs.

4. Compare the results of (Task 1) and (Task 2). What conclusions do you reach?
