Question

The mean value of land and buildings per acre from a sample of farms is $1500, with a standard deviation of $100. The data set has a bell-shaped distribution. Assume the number of farms in the sample is 78.

(a) Use the empirical rule to estimate the number of farms whose land and building values per acre are between $1300 and $1700.

___farms

Answer #1

(A) given that

mean = 1500

standard deviation (sd) = 100

and n = 78

we have to estimate the number of farms whose land and building values per acre are between $1300 and $1700.

we can write 1300 as 1500 - 2*100, i.e. it is 2 standard deviation below the mean

and we can write 1700 as 1500 + 2*100, i.e. it is 2 standard deviation above the mean

using empirical rule,we know thaty 95% of data is between 2 standard deviations from the mean

So, required number of farms = n*p

= 78*0.95

= 74.1

= 75 (rounded to next integer)
