Question

According to the empire rule, what proportion of date would lie between +1 and +2 standard deviations? (Not percentage)

Answer 1

let N be the number of observations example 1 2 3 4 5 6 7 8 9 10, N =10

0.68 *N = 6.8 about 7 data points lies in 1 std

95-68= 27% =0.27 *10 = 2.7 data points lies in 2std

To find empirical without percentages you have to know N unless i did not understand your question well
