The Honda Accord was named the best midsized car for resale value for 2018 by the Kelley Blue Book (Kelley Blue Book website). The file AutoResale contains mileage, age, and selling price for a sample of 33 Honda Accords. Click on the datafile logo to reference the data. DATA file a. Develop an estimated regression equation that predicts the selling price of a used Honda Accord given the mileage and age of the car (to 2 decimals). Enter negative value as negative number. Selling price = + Mileage + Age 20885.25 -0.04
Correlation
Correlation defines a relationship between two independent variables. It tells the degree to which variables move in relation to each other. When two sets of data are related to each other, there is a correlation between them.
Linear Correlation
A correlation is used to determine the relationships between numerical and categorical variables. In other words, it is an indicator of how things are connected to one another. The correlation analysis is the study of how variables are related.
Regression Analysis
Regression analysis is a statistical method in which it estimates the relationship between a dependent variable and one or more independent variable. In simple terms dependent variable is called as outcome variable and independent variable is called as predictors. Regression analysis is one of the methods to find the trends in data. The independent variable used in Regression analysis is named Predictor variable. It offers data of an associated dependent variable regarding a particular outcome.

Hint(s) Check My Work
The Honda Accord was named the best midsized car for resale value for 2018 by the Kelley Blue Book (Kelley Blue Book website). The
file AutoResale contains mileage, age, and selling price for a sample of 33 Honda Accords.
Click on the datafile logo to reference the data.
DATA file
a. Develop an estimated regression equation that predicts the selling price of a used Honda Accord given the mileage and age of the
car (to 2 decimals). Enter negative value as negative number.
Selling price =
20885.25
Mileage +
Age
-0.04
b. Is multicollinearity an issue for this model? Find the correlation between the independent variables to answer this question (to 2
decimals).
The correlation between age and mileage is
0.67
I. Since the correlation between the independent variables is less than 0.70, we conclude that multicollinearity is an issue.
II. Since the correlation between the independent variables is less than 0.70, we conclude that multicollinearity is not an issue.
III. Since the correlation between the independent variables is greater than 0.70, we conclude that multicollinearity is an issue.
IV. Since the correlation between the independent variables is greater than 0.70, we conclude that multicollinearity is not an issue.
II
c. Use the F test to determine the overall significance of the relationship (to 2 decimals). What is your conclusion at the 0.05 level of
significance? Use F table.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F9b35e0a5-7e0b-43df-adea-3e2a7e8bc69e%2F5f494504-e127-410c-b36a-89c31af1d46d%2Fzgv4i9_processed.jpeg&w=3840&q=75)
