![An independent consumer group published its findings 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 \( H_0 \) and the alternative hypothesis \( H_1 \) that we would use for this test.
