Question

Consider the regression model, $BILL_i = B_1 + B_2 \left(\frac{1}{FRIENDS_i}\right) + B_3 D_i + u_i$, where BILL: bill paid by a student for a post-paid mobile connection for the month of July, 2015 (in rupees) FRIENDS: number of close friends of the student $D_i = 1$ if the student's parents live in the same city = 0 otherwise The regression results are reported as follows: $BILL_i = 539 - 45 \left(\frac{1}{FRIENDS_i}\right) - 134 D_i$ (p-value) = (0.025) (0.003) (0.012) n=45 Q25. (a)Is the data time series or cross section? (b) Write the regression equations for the students whose parents stay in the same city and for students whose parents do not stay in the same city. (c)Test the statistical significance of B3 at 5% level of significance. State the null and alternative hypothesis.

          Consider the regression model, $BILL_i = B_1 + B_2 \left(\frac{1}{FRIENDS_i}\right) + B_3 D_i + u_i$,
where BILL: bill paid by a student for a post-paid mobile connection for the month of
July, 2015 (in rupees)
FRIENDS: number of close friends of the student
$D_i = 1$ if the student's parents live in the same city
= 0 otherwise
The regression results are reported as follows:
$BILL_i = 539 - 45 \left(\frac{1}{FRIENDS_i}\right) - 134 D_i$
(p-value) = (0.025) (0.003) (0.012)
n=45
Q25.
(a)Is the data time series or cross section?
(b) Write the regression equations for the students whose
parents stay in the same city and for students whose parents do
not stay in the same city.
(c)Test the statistical significance of B3 at 5% level of significance.
State the null and alternative hypothesis.

Consider the regression model, BILLi = B1 + B2 ((1)/(FRIENDSi)) + B3 Di + ui,
where BILL: bill paid by a student for a post-paid mobile connection for the month of
July, 2015 (in rupees)
FRIENDS: number of close friends of the student
Di = 1 if the student's parents live in the same city
= 0 otherwise
The regression results are reported as follows:
BILLi = 539 - 45 ((1)/(FRIENDSi)) - 134 Di
(p-value) = (0.025) (0.003) (0.012)
n=45
Q25.

parents stay in the same city and for students whose parents do
not stay in the same city.
(c)Test the statistical significance of B3 at 5% level of significance.
