Extracted text: A New York Times article noted that the mean life span for 40 male symphony conductors was 74.3 years, in contrast to the mean of 72.4 years for males in the general population. Assuming that the 40 males have life spans with a standard deviation of 8.9 years, use a 0.05 significance level to test the claim that male symphony conductors have a mean life span that is greater than 72.4 years. Which is the proper expression of Ho? H = 72.4 Ο μ<72.4 o="" µ=""> 72.4 Ο μ> 72.4 Which is the proper expression of H1? O µ> 72.4 p = 72.4 Ο μ<72.4 ο="" μ=""> 72.4 What type of test is called for here? State teritical Correct to 4 decimal places? Determine the t test-statistic, correct to 4 decimal places: Determine the p-value, correct to 4 decimal places: Conclusion: O Do not reject Ho O Reject Ho
