Please answer questions 4 and 5 only !!!

thank you

the data from quest 3 is:

Answer 1

4)
a)
p-value of slope = 0.00

if p-value < alpha, we reject the null hypothesis
if p-value > alpha, we fail to reject the null hypothesis

since p-value < alpha, we reject the null hypothesis

b)
TS = b0^/se(b0^)
= -33716/1204.31    {Standard error has been incorrectly printed, it is exchanged}
= -27.996

critical value = -1.96

since |TS| = 27.996 > 1.96
we reject the null hypothesis
hence intercept is statistically significant

Please give me a thumbs-up if this helps you out. Thank you! :)
