The mean value of land and buildings per acre from a sample of farms is $1300

, with a standard deviation of $300

. The data set has abell-shaped distribution. Assume the number of farms in the sample is 73

(a) Use the empirical rule to estimate the number of farms whose land and building values per acre are between $1000

and $1600

farms (Round to the nearest whole number asneeded.)

(b) If 26

additional farms weresampled, about how many of these additional farms would you expect to have land and building values between $1000

per acre and $1600

peracre?

farms out of 26

26 (Round to the nearest whole number asneeded.)
