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 660 days and a standard deviation of 122.5. BIG Corporation claims that the standard deviation of its electric bulbs is less than 122.5. Suppose that we want to carry out a hypothesis test to see if BIG Corporation's claim is correct. State the null hypothesis H. and the alternative hypothesis H, that we would use for this test. H: O H₁:0 μ ô 4 |x X O Р S OO 020
