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 18 internet speeds from around the nation. The observations are given below. 95 101 88 110 87 91 88 103 91 83 94 83 87 87 87 82 97 100 Using a significance level of 0.05%, 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. Determine the test statistic. Round the solution to four decimal places.

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 18 internet speeds from around the nation. The observations are given below.

95 101 88 110 87 91 88 103 91
83 94 83 87 87 87 82 97 100



Using a significance level of 0.05%, 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.



Determine the test statistic. Round the solution to four decimal places.
