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, â6) is rotated 90° counterclockwise. (x, y) â (ây, x) 1. switch the x- and y-coordinates: (6, â3) 2. multiply the new x-coordinate by â1: (6(â1), â3) 3. simplify: (â6, â3) .

Arandom sample of n = 25 observations is taken from a n(µ, Ï ) population. a 95% confidence interval for µ was calculated to be (42.16, 57.84). the researcher feels that this interval is too wide. you want to reduce the interval to a width at most 12 units. a) for a confidence level of 95%, calculate the smallest sample size needed. b) for a sample size fixed at n = 25, calculate the largest confidence level 100(1 â α)% needed.
