Question 1123848
Q: The mean value of land and buildings per acre from a sample of farms is
$2400, with a standard deviation of $450. Between what two values do about
95% of the data lie? 
--------------------------------
Solution:
According to the Empirical Rule and assuming normality (or at least approximately normal), about 95% of observations lie within 2 standard deviations of the mean. Therefore, about 95% of the values lie between ${{{highlight(1500)}}} and ${{{highlight(3300)}}}
