Answer: 68.27%
Step-by-step explanation:
Given : Mean value of land and buildings per acre from a sample of farms :
The data set has a bell-shaped distribution. i.e. it follows Normal distribution.
Using , for x= 1300 , we have
For x= 1700 ,
Using standard normal z-value table,
P-value = P(-1<z<1)= [Round to nearest 4 decimal places.]
i.e. The percent of farms whose land and building values per acre are between $1300 and $1700 = 68.27%
