(In some of the exercises that follow, we must make assumptions of normal distributions with the usual notation.)
Let X and Y have a bivariate normal distribution with correlation coefficient ρ. To test H0: ρ = 0 against H1: ρ ≠ 0, a random sample of n pairs of observations is selected. Suppose that the sample correlation coefficient is r = 0.68. Using a significance level of α = 0.05, find the smallest value of the sample size n so that H0 is rejected.
