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 level of significance to test the claim that male symphony conductors have a mean life span that is different from 69.5 years. (See also Exercise 13 in Section 1-3.)

Contingency Table
A contingency table can be defined as the visual representation of the relationship between two or more categorical variables that can be evaluated and registered. It is a categorical version of the scatterplot, which is used to investigate the linear relationship between two variables. A contingency table is indeed a type of frequency distribution table that displays two variables at the same time.
Binomial Distribution
Binomial is an algebraic expression of the sum or the difference of two terms. Before knowing about binomial distribution, we must know about the binomial theorem.

Transcribed Image Text: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
level of significance to test the claim that male symphony conductors have
a mean life span that is different from 69.5 years. (See also Exercise 13 in
