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%
Answer:
Kindly check explanation
Step-by-step explanation:
Given the regression equation :
y = 31.6 + 10.9x
x = the number of years of study ;
y = the grade on the test.
The predicted is y which is also the same as the response variable, hence, the response variable is grade on the test
The predictor variable is x, which is the independent variable, which is the number of years of study.
From. The regression output given ;
The slope which is the Coefficient of the predictor variable is 10.9 which means that for every unit change in number of years of study, the grade on test increases by 10.9
The intercept which is the constant value, 31.6, means, the least a person can get in the get in grade is 31.6 (at x = 0)
