Write the hypotheses.
-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 are A. $H _ { 0 } : \mu = 77$ and $H _ { A } : \mu > 77$
B. $H _ { 0 } : \mu = 77$ and $H _ { A } : \mu < 77$
C. $H _ { 0 } : \mu = 77$ and $H _ { A } : \mu \neq 77$
D. $H _ { 0 } : p = 77$ and $H _ { A } : p > 77$
E. $H _ { 0 } : p = 15$ and $H _ { A } : p < 77$
