Question
Is my hypothesis correct & I'm confused on whether I accept or reject the null hypothesis.
The p-value for the MPG is given as 0.0017, the p-value for the reliability is given as 0.2453 and the p-value for the variable safety is 0.00002.
State the hypotheses being tested
The independent variables do not have a statistically significant impact on the price of a car.
H0 : 1 = 2 = 3 = 0
The independent variables do have a statistically significant impact on the price of a car.
HA : At least one i 0 (for i = 1, 2, 3)
Also how would I write this hypothesis test out in notation format?
Null hypothesis: H0: A significant linear relationship does not exist between the dependent variable price of the car and the independent variables MPG, reliability and safety of the car.
Alternative hypothesis: Ha: A significant linear relationship exists between the dependent variable price of the car and the independent variables MPG, reliability and safety of the car.
Explanation / Answer
The p-value for the MPG is given as 0.0017, the p-value for the reliability is given as 0.2453 and the p-value for the variable safety is 0.00002.

H0 : 1 = 2 = 3 = 0
The independent variables do have a statistically significant impact on the price of a car.
HA : At least one i 0 (for i = 1, 2, 3)
from above P values
all are significant except the reliability.
