Question

A study of 17 worldwide financial institutions showed the correlation between their assets and pretax profit to be 0.78.

a. State the decision rule for 0.025 significance level: H₀: ρ ≤ 0; H₁: ρ > 0. (Round your answer to 3 decimal places.)

b. Compute the value of the test statistic. (Round your answer to 2 decimal places.)

c. Can we conclude that the correlation in the population is greater than zero? Use the 0.025 significance level.

Definition Definition Relationship between two independent variables. A correlation tells the degree to which variables move in relation to each other. When two sets of data are related to each other, there is a correlation between them.
