Asimple random sample of 60 adults is obtained from a normally distributed population, and each person's red blood cell count (in cells per microliter) is measured. the sample mean is 5.25 and the sample standard deviation is 0.55. use a 0.05 significance level and the given calculator display to test the claim that the sample is from a population with a mean less than 5.4 comma which is a value often used for the upper limit of the range of normal values. what do the results suggest about the sample group?

Mary beth used the mapping rule to find the coordinates of a point that had been rotated 90Β° counterclockwise around the origin. examine the steps to determine whether she made an error. m (3, β6) is rotated 90Β° counterclockwise. (x, y) β (βy, x) 1. switch the x- and y-coordinates: (6, β3) 2. multiply the new x-coordinate by β1: (6(β1), β3) 3. simplify: (β6, β3) .
