Explanation / Answer

g) Capital= -465.2883+228.8306*Rental

Y'= b0+b1*X

a) if rental value=0

Capital= -465.2883 or b0 dollers and statement is right.

b) if rental= 1000 is b0 dollers

Capital= -465.2883+228.8306*1000= 228365.312, statement is wrong

c) if rental= 1000 is b0 1000dollers

Capital= -465.2883+228.8306*1000= 228365.312

b0 1000= 1000, wrong statement

d) Capital= 0 is b0 is 1000 dollers

0=-465.2883+228.8306*rental=> rental= 2.0333, wrong

e)if rental =0 is b0 1000 dollers

Capital= -465.2883 or b0 dollers

Answer: A

h) Yes, intercept interpretation is if rental unit is zero then predicted capital will be b0 value.

i)With the context of given data, Intercept value is meaning full with R-squared 0.624992 or 62.4992%

and relation ship with output variable t-value is also significant with lessthan 0.05 p-value.

Data is positively correlated that per every additional rental unit, capital value also increases at 228.8306 per unit.
