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 variance of 15,006.25. BIG Corporation claims that the variance of its electric bulbs is less than 15,006.25. 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. Ho: L H,: 0
