Insurance companies track life expectancy information to assist in determining the cost of life insurance policies. Last year the average life expectancy of all policyholders was 77 years. ABI Insurance wants to determine if their clients now have a longer life expectancy, on average, so they randomly sample some of their recently paid policies. The insurance company will only change their premium structure if there is evidence that people who buy their policies are living longer than before. The correct null and alternative hypotheses areoptions:a. H0: p = 77 and HA: p > 77b. H0: %u03BC = 77 and HA: %u03BC < 77c. H0: %u03BC = 77 and HA: %u03BC > 77d. H0: %u03BC = 77 and HA: %u03BC %u2260 77e. H0: p = 15 and HA: p < 77
