The mean value of land and buildings per acre from a sample of farms is $1600, with a standard deviation of $300. 

The data set has a bell shaped distribution. Assume the # of farms in the sample is 70.

Use the empirical rule to estimate the # of farms whose land and building values per acre are b/w $1000-2200 ______________ farms

If 20 additional farms were sampled about how many of these additional farms would you expect to have land and building values b/w $1000 per acre and $2000 per acre________ farms out of 20.
