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
