random sample of size 32 is selected from population X, and a random sample of size 43 is selected from population Y. A 90 percent confidence interval to estimate the difference in means is given as (−1.25,0.87)(−1.25,0.87). Consider a change in the sample sizes such that a random sample of size 52 is selected from population X and a random sample of size 63 is selected from population Y. When all other things remain the same, what effect would such a change have on the interval? A) The width of the interval will increase. B) The width of the interval will decrease. C) The interval will contain no negative numbers. D) The level of confidence will increase. E) The sample means will increase
