Consider the following.
(a) Compute the estimate for the standard error of difference between two independent means for s1^2 = 17, s2^2 = 10, n1 = 30, and n2 = 26. (Give your answer correct to two decimal places.)
(b) Calculate the estimate for the standard error of difference between two independent means for s1^2 = 0.046, s2^2 = 0.092, n1 = 5, and n2 = 14. (Give your answer correct to four decimal places.)
(c) Calculate the estimate for the standard error of difference between two independent means for s1 = 3.3, s2 = 6.1, n1 = 15, and n2 = 22. (Give your answer correct to two decimal places.)
