Question 5 and Question 6
Step 1 - Put the data in excel as shown and arrange the variables as shown
Step 2 - Select the regression option from the data analysis tab
Step 3- Input the values as shown below.
Step 4 - The output is generated as follows.
The regression equation ( This equation is obtained from coefficient of the regression output. Highlighted in green)
Regression equation
List price = 12267 - 0.0414 Milage
Question 7
The slope of the regression equation is - 0.0414.
With one unit increase in the mileage, the price decreases by 0.0414.
Question 8
correlation = -0.3824
It is negative correlation or an inverse relationship. As one increases the other one decreases.
Question 9 : Need background to the problem
Question 10
Yes we can conclude that the mileage causes the price of used car
to go down. We see that the pvalue of the anova output is less than
0.05,hence indicate that the relationship is significant.
