Mark the statement below as True or False. If you believe that a statement is false, briefly say why you think it is false. If the two sample standard deviations are essentially the same s_1^2 s_2^2, then the pooled two-sample interval will agree with the regular two-sample interval for the difference in the means. Choose the correct answer below.

Solution

(A) True Since when we are testing for the difference between two means of normal variables ,the pooled estimate of the variance here becomes almost equal to one or two of the variances and will leave no different effect on the testing the same with regular intervals.
