Question
A national internet service provider (ISP) claims that its broadband internet download speed is 100
megabits per second (Mbps) on average. To the contrary, there have recently been widespread reports that
consumers are experiencing much slower download speeds from this ISP. A organization ogranization
decided to investigate the issue. They took a random sample of 16 internet speeds from around the nation.
The observations are given below.

Using a = 0.1, test the hypothesis that the average download speed is 100 Mbps, as advertised by the ISP.
Assume that the distribution of all broadband internet download speed measurements from this ISP is
approximately normally distributed. Use the critical value method.

Determine the critical value(s) for this hypothesis test. Round the solution(s) to four decimal places. If
more than one critical value exists, enter the solutions using a comma-separated list.
