Please help, I don't know how to calculate the percentage of data that falls between the first, second, and third standard deviation on my dot plot!How do I calculate the percentage of the data the falls between the first standard deviation of the mean?
Refer to the graph and table in the pic http://business.statistics.sweb.cz/norma鈥?/a>
At 1 SD, probability is .8413
Ar 2 SD, probability is .9773
Ar 3 SD, probability is .9986
Between 1st %26amp; 2nd: .9773 - .8413 = .136 which is 13.6%
between 1st %26amp; 3rd: .9986 - .8413 = .1573 which is 15.73 %
between 2st %26amp; 3rd: .9986 - .9773 = .0213 which is 2.13 %
