And replacing we got:

Then we can fin the limits for one deviation within the mean like this:

And then we see that the number of values between the limits are: 69, 64, 54,47 who represent 4 and then the percentage would be:

Step-by-step explanation:

First we need ot calculate the mean and deviation with the following formulas:

And replacing we got:

Then we can fin the limits for one deviation within the mean like this:

And then we see that the number of values between the limits are: 69, 64, 54,47 who represent 4 and then the percentage would be:
