The mean value of land and buildings per acre from a sample of farms is $1500,with a standard deviation of $200. The data set has abell-shaped distribution. Assume the number of farms in the sample is 79.

(a)Use the empirical rule to estimate the number of farms whose land and building values per acre are between $1300and $1700?. ___(Round to the nearest whole number asneeded.)

(b) If 28additional farms weresampled, about how many of these additional farms would you expect to have land and building values between $1300per acre and $1700 peracre? ___farms out of 28(Round to the nearest whole number)
