Question

A New York Times article noted that the mean life span for 35 male symphony conductors was 73.4 years, in 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?
O µ< 69.5
O µ> 69.5
Ο μ>69.5
Ο μ- 69.5
Which is the proper expression of H1?
