Question 1162664: 1. The mean value of land and buildings per acre from a sample of farms is $1600 , with a standard deviation of $200. The data set has a bell shaped distribution. Use the empirical rule and estimate the percent of farms whose land and building values per acre are between $1000 and $2200

z=(x-mean)/sd
so between 1000 (-3 sd) and 2200 (+3 sd), there would be 99.7% chance by the empirical rule.
