A study of 26 worldwide financial institutions showed the correlation between their assets and pretax profit to be 0.87. 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.
