For a two-tailed independent-measures t test with sample sizes 7 and 5, the 99% confidence interval for the population mean difference is -1< μ1- μ2 <9 . If M1=31. Find M2 and SM1-M2

What is the smallest integer n such that n\sqrt{2} is greater than 20

Mary beth used the mapping rule to find the coordinates of a point that had been rotated 90° counterclockwise around the origin. examine the steps to determine whether she made an error. m (3, –6) is rotated 90° counterclockwise. (x, y) → (–y, x) 1. switch the x- and y-coordinates: (6, –3) 2. multiply the new x-coordinate by –1: (6(–1), –3) 3. simplify: (–6, –3) .
