For the above example, (0.33, 0.97) is a 95% confidence interval for the population correlation coefficient . Note that 0.4 is within the interval. With small sample sizes, the sample correlation coefficient can be quite different from the population value as reflected in the estimated standard deviation (see Equation 9).
