'A New York Times article noted that the mean life span for 35 male symphony conductors was 73.4 years, contrast to the mean of 69.5 years for males in the general population Assuming that the 35 males have life spans with a standard deviation of 8.7 years, use a 0.05 significance level to test the claim that male symphony conductors have a mean life span that is greater than 69.5 years:
Which is the proper expression of Ho?
p < 69.5
p > 69.5
p 2 69.5
p = 69.5
Which is the proper expression of Hi?
p >69.5
p > 69.5
p = 69.5
H < 69.5
What type of test is called for here?

Determine the p-value; correct to 4 decimal places:
Conclusion:
Reject Ho
Do not reject Ho'
