The mean is simply the arithmetic average of all your raw data. This can be solved methodically by summing up all of the raw data points that you have. Take note how many raw data points you used, because this will be used to divide the sum. You will obtain the mean.

Answer:
The number of neutrons are different.
Explanation: -
In 17O
The mass number is 17
The atomic number for oxygen = 8
Number of neutrons of 17O = Mass number of 17O – atomic number
= 17-8
=9
In 16O
The mass number is 16
Number of neutrons of 16O = Mass number of 16O – atomic number
= 16-8
=8
The mass number is 18
The atomic number for oxygen = 8
Number of neutrons of 18O = Mass number of 18O – atomic number
= 18-8
=10
As we can see the number of neutrons are different in each case.
