[QUOTE="lanceharbor05, post: 2764764, member: 921125"] If you have 85% inside the interval, then you'll have 15% outside the interval. 7.5% above 7.5% below Find the z-score that corresponds to 0.075 (I'm using microsoft Excel to find this one, you can approximate it on a z-table) z = -1.4395 so, basically, it will be 1.43 standard deviations above and below the mean that contains 85% of the data [/QUOTE]
