An independent consumer group published its finding that the lifetimes of electric bulbs manufactured by BIG Corporation are approximately normally distributed with a mean of 620 days and a standard deviation of 124.5 . BIG Corporation claims that the standard deviation of its electric bulbs is less than 124.5. Suppose that we want to carry out a hypothesis test to see if BIG Corporation's claim is correct. State the null hypothesis H0 and the alternative hypothesis H1that we would use for this test. H0: H1:
