Consider the data presented in Table 1 below.

Table1 Financial data on 6 families

Consumption expenditures (per week)= C Disposable income (per week)= I

$680$ 900

8001100

8301000

8901200

9201500

9601800

If expresses a relationship between consumption expenditures and disposable income and assuming that satisfies all the conditions of the Gauss-Markov theorem, use the sample of data in Table 1 to

a)estimate the regression parameters;

b)calculate the sum of the squared residuals;

c)calculate the standard error of estimate;

d)compute the standard error of ;

e)calculate ;

f)test the null hypothesis against the alternative .

can you please help me step by step?
