How long does it take for a chunk of information to travel from one server to another and back on the Internet? According to the site internettrafficreport. com, the average response time is 200 milliseconds (about one-fifth of a second). Researchers wonder if this claim is true, so they collect data on response times (in milliseconds) for a random sample of 14 servers in Europe. A graph of the data reveals no strong skewness or outliers. We want to test
0::=200≠200

where = the true mean response time of European servers.

The 95% confidence interval for the mean response time is 158.22 to 189.64 milliseconds. Based on this interval, what conclusion would you make for a test of the given hypotheses at the =0.05 significance level?

A We fail to reject 0 at the =0.05 significance level. We do not have convincing evidence that the mean response time of European servers is different from 200 milliseconds.

B We reject 0 at the =0.05 significance level. We have convincing evidence that the mean response time of European servers is greater than 200 milliseconds.

C We reject 0 at the =0.05 significance level. We do not have convincing evidence that the mean response time of European servers is different from 200 milliseconds.

D We fail to reject 0 at the =0.05 significance level. We have convincing evidence that the mean response time of European servers is 200 milliseconds.

E We reject 0 at the =0.05 significance level. We have convincing evidence that the mean response time of European servers is different from 200 milliseconds.
