Sofia is painting a picture for a school project. She goes to the store and purchases a rectangular canvas to paint on. If the canvas has a length of 5 inches and a width of 5 inches, how many square inches is the area of the canvas?

Arandom sample of n = 25 observations is taken from a n(µ, σ ) 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 − α)% needed.
