this question gives you a list of a couple numbers and asks you to find the mean the numbers that it gives our eight, 10 16 21 and 25. Now we know the mean. Our X bar is just the sum of all the exes over the number. And here we we know that n is equal to five. And if you plug all of these into your calculator, add them up will find that the sum of all the exes is equal to 80. So x bar, the mean is equal to 80/5 or 16.
