Unformatted text preview: 1. Find the two critical values (alpha/2 and 1alpha/2) 2. Compute the value for the population variance given above. 3. Place the population variance between the two values calculated in step 2 (put the smaller one first). Note, the lefthand endpoint of the confidence interval comes when the right critical value is used and the righthand endpoint of the confidence interval comes when the left critical value is used. This is because the critical values are in the denominator and so dividing by the larger critical value (right tail) gives the smaller endpoint....
