Refer to the accompanying data display that results from a sample of airport data speeds in Mbps. Complete parts (a) through (c) below. Tinterval (13.046,22.15) x= 17.598 Sx=16.01712719 n=50 a. Express the confidence interval in the format that uses the "less than" symbol. Given that the original listed data use one decimal place, round the confidence interval limits accordingly. 13.05 Mbps<< 22.15 Mbps (Round to two decimal places as needed.) b. Identify the best point estimate of u and the margin of error. The point estimate of juis Mbps. (Round to two decimal places as needed.)
