WHAT DOES IT ALL MEAN? When X =4 and S =1.41 68% of the data ranges between 2.59 ~ 5.41. X + 15 -> 4 +1.41 =(2.59 -5.41) 95.5% of the data ranges between 1.18 ~ 6.82, X = 25 -> 4 = (2)1.41 = (1.18 -6.55) * Numerically we round the Ranges in the following way. Fill in the blanks below. 68% Range = X + 15 > 2.59 ~ 5.41 95% Range = X + 25 > 1.18 ~ 6.82 99.7% Range = X + 35 > 99.9% Range = X + 45 >
