the regression equation netincome = 2,277 + .0307 revenue was estimated from a sample of 100 leading world companies (variables are in millions of dollars). (a-1) calculate the residual for the x, y pair ($41,078, $8,301).

Sagot :

From a sample of 100 leading world companies we can estimate the residual value is 4,762.9054 .

It is given that,

Regression equation net income = 2277+0.0307

From a sample of 100 leading world companies we can estimate the revenue.

(a-1)

for the (x,y) pair, x = $41,078 and y = $8,301 or it is represented as ($41,078 , $8,301)

then the above (x,y) pair's residual value is e = y - ÿ

ÿ = 2277+0.307x

= 2277+0.0307(41078)

= 2277+1261.0946

= 3538.0946

Thus, e = y - ÿ

so, e = 8301 - 3538.0946

= 4762.9054

Hence, the residual value = 4,762.9054                                                                                  

To calculate the correlations between a dependent variable and one or more independent variables, a statistical technique grouping together several statistical techniques known as regression analysis is utilized. Revenue is the entire amount of money received from the sale of goods or services related to a company's main operations. Revenue, also known as gross sales, is often referred to as the "top line" because it appears at the top of the income statement. The residual value, also known as salvage value, is the estimated value of a fixed asset at the end of its useful life or lease term.
