Question: A random sample of 94 light bulbs had a mean life of \(\bar{X}\) = 587 hours. The standard deviation of the lifetime of all such light bulbs is of \(\sigma \) = 36 hours.
It was expected that the mean lifetime of the light bulbs was 600 hours. Do the results contradict expectations? Explain your answer.
