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 375.00 hours at a 95.00% confidence level. The STDEV.P = 100.00 hours. A random sample of 64 light bulbs indicate a MEAN.S of 350.00 hours. What will be the hypothesis of the study? What will be the area of rejection in this study using the Z Stat critical value? Create the statement of rejection and non-rejection based upon the Z Stat value and the Z Stat critical value What will be the conclusion of the study? (check figure: Z Stat = -2.00)
