Refer to the technology output given to the right that results from measured hemoglobin levels​ (g/dL) in100 randomly selected adult females. The confidence level of 90​% was used.   a. Express the confidence interval in the format that uses the​ "less than" symbol. Assume that the original listed data use two decimal​ places, and round the confidence interval limits accordingly. b. Identify the best point estimate of μ and the margin of error. c. In constructing the confidence interval estimate ofm μ​,why is it not necessary to confirm that the sample data appear to be from a population with a normal​ distribution?     TInterval (13.165,13.625) x=13.395 Sx=1.388 n=100
