The second question I need help with.

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 a bell-shaped distribution. Assume the number of farms in the sample is 77. 53 farms (Round to the nearest whole number as needed.) (b) If 24 additional farms were sampled, about how many of these additional farms would you expect to have land and building values between $1000 per acre and $1600 per acre? farms out of 24 (Round to the nearest whole number as needed.)
