The mean value of land and buildings per acre from a sample of farms is $1800, with a standard deviation of $300. The data set has abell-shaped distribution. Assume the number of farms in the sample is 72.

(a) Use the empirical rule to estimate the number of farms whose land and building values per acre are between $1500 and $2100.

nothing

farms (Round to the nearest whole number asneeded.)

(b) If 29 additional farms weresampled, about how many of these additional farms would you expect to have land and building values between $1500 per acre and $2100 peracre?

nothing

farms out of 29 (Round to the nearest whole number asneeded.)
