Question

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 overbarxequals=17.598 Sxequals=16.01712719 nequals=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.

Answer 1

Answer:

13.05MbpS < x < 22.15 Mbps

Step-by-step explanation:

Confidence interval CI can be expressed in the form;

Lower bound < x < upper bound

Given;

CI = (13.046, 22.15)

Lower bound = 13.046 = 13.05 Mbps (to two s.f.)

Upper bound = 22.15 Mbps

So, the Confidence interval is given as;

13.05 MbpS < x < 22.15 Mbps
