Question 1150820: The mean value of land and buildings per acre from a sample of farms is $1600, with a standard deviation of $100. The data set has a bell-shaped distribution. Assume the number of farms in the sample is 78.
Use the empirical rule to estimate the number of farms whose land and building values per acre are between $1500 and $1700.
18 farms (Round to the nearest whole number as needed.) Answer by Boreal(15235) (Show Source):
You can put this solution on YOUR website! This is between +/- 1 sd or 68% of the population of 78 from theses data.
78*0.68=53.03
53 farms.
