Consider the following.

Using the figure shown above, find the 95% interval when a sample of n = 100 results in r = 0.35. (Round your answers to two decimal places.)

Solution

The sample size is n=100 and r=0.35. First find r=0.35 at the bottom of the table. Visualize a vertical line through this point. Find the points then where the belt marked for the correct sample size crosses the vertical line. The two values are 0.1 and 0.5.

Thus the 95% interval is (0.1,0.5)
