I want to know if the last part is correct (Bold)

What is the​ F-statistic?
 
F=13.4913.49
​(Round to two decimal places as​ needed.)
 
What is the​ P-value?
 
P=00
​(Round to three decimal places as​ needed.)
 
Since the​ P-value is less than or equal to the significance​ level,
reject H0. The data provide sufficient evidence to conclude that the population means are not all the same.
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
