Refer to the technology output given to the right that results from measured hemoglobin levels (g/dL) in 100 randomly selected adult females. The confidence level of 95% was used. Tinterval (12.858,13.446) x= 13.152 Sx = 1.481 n = 100 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 u and the margin of error. c. In constructing the confidence interval estimate of u, why is it not necessary to confirm that the sample data appear to be from a population with a normal distribution? ... 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. g/dL < < g/dL (Round to three decimal places as needed.) -
