Question 919415: The mean value of land and buildings per acre from a sample of farms is $1200, with a standard deviation of $300. The data set has a bell-shaped distribution. Assume the number of farms in the sample is 72.
Use the empirical rule to estimate the number of farms whose land and building values per acre are between $600 and $1800. Answer by ewatrrr(24785) (Show Source):
You can put this solution on YOUR website! mean = $1200, with a standard deviation of $300.
$600 < x < $1800
2Sds on either side of mean
one standard deviation from the mean accounts for about 68% of the set
two standard deviations from the mean account for about 95% ****
and three standard deviations from the mean account for about 99.7%.
