The mean value of land and buildings per acre from a sample of farms is $1700 with a standard deviation of $300

300. The data set has abell-shaped distribution. Assume the number of farms in the sample is 80

a) Use the empirical rule to estimate the number of farms whose land and building values per acre are between $1100 and $2300

(b) If 28 additional farms weresampled, about how many of these additional farms would you expect to have land and building values between $1100 per acre and $2300 peracre?
