use the Tormula to Tinu the standard error Of the distribution Of UmTererices In Sample means, X1 - X2. Samples of size 115 from Population 1 with mean 87 and standard deviation 13 and samples of size 85 from Population 2 with mean 74 and standard deviation 17 Round your answer for the standard error to two decimal places. standard error = eTextbook and Media Hint Assistance Used When choosing random samples of size n, and n2 from populations with means u, and /2 and standard deviations of and 62, respectively, the distribution of the differences in the two sample means, x1 - X2, is approximately normal if both sample sizes are large (at least 30), is centered at /1 - /2, and has standard deviation SE = n1 n2 Save for Later Attempts: 0 of 3 used Submit
