Thank you SO much!

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 lim
accordingly.
O Mbps <u<O 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 uµ is O Mbps.
(Round to two decimal places as needed.)
The margin of error is E =O Mbps.
(Round to two decimal places as needed.)
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?
