The regression equation netincome = 2,159 + .0312 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 ($45,533, $2,697). (a negative value should be indicated by a minus sign. round your answer to 4 decimal places.) residual
(a-2) did the regression equation underestimate or overestimate the net income? the regression equation overestimated the net income. the regression equation underestimated the net income.
(b-1) calculate the residual for the x, y pair ($60,417, $3,497). (a negative value should be indicated by a minus sign. round your answer to 4 decimal places.) residual
(b-2) did the regression equation underestimate or overestimate the net income? the regression equation overestimated the net income. the regression equation underestimated the net income.

a) -882.6296

b) The regression equation overestimated the net income.

c) -547.0104

d) The regression equation overestimated the net income.

Step-by-step explanation:

We are given the following information in the question:

The regression equation for net income is given by:

a)  residual for the (x, y) pair ($45,533, $2,697)

Calculated net income =

Residual = Observed net income - Calculated net income

b)  The regression equation overestimated the net income.

c)  residual for the (x, y) pair ($60,417, $3,497)

Calculated net income =

Residual = Observed net income - Calculated net income

d)  The regression equation overestimated the net income.

step-by-step explanation:

whole numbers.

step-by-step explanation:

we are given the average monthly rainfall (in millimeters) model r(m) for the years 1900-2009 as a function of the month number m.

as we can see m is taken for the number of months for years 1900-2009.

we know that number of months can't be a negative number or decimal number or a fraction.

so, the number of months could be only positive whole numbers.

therefore, whole numbers is more appropriate for the domain of r.
