Given n pairs of data from which the linear correlation coefficient r can be found, use the following procedure to construct a confidence interval about the population parameter p.
Step a. Use Table A-2 to find za/2 that corresponds to the desired degree of confidence.
Step b. Evaluate the interval limits wL and wR:

Step c. Now evaluate the confidence interval limits in the expression below:

Use this procedure to construct a 95% confidence interval for p, given 50 pairs of data for which r = 0.600.
