A consumer believes that it is actually less and plans to test this by assessing the lifetime of bulbs on a sample of 35 bulbs and tests these assumptions at significance level of 0.05. If the standard deviation of bulb life is 4000 hours, what is the probability of a type II error if the actual mean lifetime of the bulb is 33000 hours?

(ii) Given that the significance level is 0.005, what is the probability of a type II error if the actual mean lifetime of the bulb is 32500 hours?
