Step 1
- Null hypothesis (\(H_0\)): There is no positive correlation in the population, i.e., \(\rho = 0\). - Alternative hypothesis (\(H_a\)): There is a positive correlation in the population, i.e., \(\rho > 0\). Show more…

A study of 27 worldwide financial institutions showed the correlation between their assets and pretax profit to be 0.88. a. State the decision rule for a significance level of 0.100: 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 3 decimal places.) c. Can we conclude that the correlation in the population is greater than zero? Use the 0.100 significance level.

A study of 28 worldwide financial institutions showed the correlation between their assets and pretax profit to be 0.89. a. State the decision rule for 0.050 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.)
