Refer to the technology output given to the right that results from measured hemoglobin levels Tlnterval (gldL) in 100 randomly selected adult females. The confidence level of 90% was used. l12.803,13.245) x = 13.024 a. Express the condence interval in the format that uses the \"less than" symbol. Assume that the Sx = 1333 original listed data use two decimal places, and round the confidence interval limits accordingly. n = 100 b. Identify the best point estimate of p and the margin of error. c. In constructing the condence interval estimate of p, why is it not necessary to conrm that the sample data appear to be from a population with a normal distribution? (I) a. Express the condence 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. D gldL
