0 / 2.5 Your answer is incorrect. Use the formula to find the standard error of the distribution of differences in sample means, X1 - X2. Samples of size 120 from Population 1 with mean 84 and standard deviation 13 and samples of size 75 from Population 2 with mean 77 and standard deviation 18 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 / and /2 from populations with means /, and u2 and standard deviations of and 62. respectively, the distribution of the differences in the two sample means, $1 - $2, is approximately normal if both sample sizes are large (at least 30), is centered at /1 - //2, and has standard deviation SE = n2 Attempts: 1 of 3 used Submit Answer 7:47 P e to search W 620F Sunny ~ D (740) 4/6/20
