The mean value of land and buildings per acre from a sample of farms is $1300, with a standard deviation of $100. the data set has a bell-shaped distribution. assume the number of farms in the sample is 76. (a) use the empirical rule to estimate the number of farms whose land and building values per acre are between $1100 and $1500.

answer: 5

step-by-step explanation:

since, the range is the difference between the lowest and highest values of the given sample space.

and, here the sample space = { 3, 1, 0, 4, 1, 4, 2, 3, 0, 5, 0, 1, 1, 2, 0, 4, 1,4, 4 ,2 ,3 ,2 ,0 ,1 ,4 }

here, the highest value of the given sample = 5

and, the lowest value = 0

therefore, the range of the sample space = 5 - 0 = 5
