Compute the coefficient

of rank co

rrelatio

n between the two variables.

the .01 significance level, can you

conclude that it is greater than

zero?

Assume that the distributions of

team salaries for the American

League and National

League do not

follow the normal distribution.

Conduct

a test of hypothesis to see

whether there is a difference in

the two distributions.

correlation between

these two variables. At the .05

nable to

conclude the ranks of these two

variables are related
