Question 459097: Write the claim mathematically, identify Ho and Ha, find critical values and rejection regions. Use them to answer the question.
A light bulb manufacture guarantees that the mean life of bulbs is at least 750 hours with a standard deviation of 60 hours. At alpha = 0.02, do you have enough evidence to reject his claim? Answer by jim_thompson5910(35256) (Show Source):
