Answer:
b) y = 289.815 when
Step-by-step explanation:
We are given the following information in the question:
where y is the dependent variable,
are the independent variable.
The multiple regression equation is of the form:
where,
: is the intercept of the equation and is the value of dependent variable when all the independent variable are zero.
: It is the slope coefficient of the independent variable
.
: It is the slope coefficient of the independent variable
.
- The regression coefficient in multiple regression is the slope of the linear relationship between the dependent and the part of a predictor variable that is independent of all other predictor variables.
Comparing the equations, we get:
- This means holding
constant, a change of one in
is associated with a change of 0.5906 in the dependent variable.
- This means holding
b) We have to estimate the value of y
Answer:
Step-by-step explanation:
Given:
'C' represent total cost of lease. 'd' represents cost of sales in dollars.
Cost of 1 square foot of building = $0.75
Total area of the building = 500 square feet.
Sales tax on the total sales = 2.5%
Now, cost of 500 square feet area = Cost of 1 square foot × Total area
Cost of 500 square feet area =
Now, sales tax is 2.5 of total sales 'd'. This gives,
Sales tax =
Now, total cost is the sum of least amount and total sales tax.
Total cost = Least amount + Sales tax
⇒
