To see how much difference time of day made on the speed at which he could download files, a college sophomore placed a file on a remote server, then proceeded to download it at three different time periods of the day. He downloaded the file 18 times in all, 6 times at each time of day, and recorded the time in seconds that the download took. At the 5% significance level, do the data provide sufficient evidence to conclude that a difference exists in mean download speed?
