The following hypotheses are given.H0: ρ ≤ 0H1: ρ > 0
a. State the decision rule for 0.025 significance level. (Round your answer to 3 decimal places.) Reject Ho if t> b. Compute the value of the test statistic. (Round your answer to 3 decimal places.) Value of the test statistic is c. Can we conclude that the correlation in the population is greater than zero? Use the 0.025 significance level. Ho. We conclude that the correlation in the population is zero.
