For the paired data below, do a complete regression analysis: a) Compute the value of the correlation coefficient. b) Use the Critical Value (CV) from the table to determine if there is a significant linear correlation. c) Determine the linear regression equation
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.

![### Real Estate Data Analysis
Below is a table showcasing the relationship between the size of properties (in square feet) and their corresponding asking prices. This data is useful for analyzing how property size affects pricing and can assist in understanding market dynamics.
| Size (sq. ft.) | 1,284 | 940 | 3,408 | 780 | 1,616 | 924 | 1,593 | 650 | 1,056 | 1,783 |
|-----------------|-------|-----|-------|-----|-------|-----|-------|-----|-------|-------|
| Asking Price ($)| 215 | 190 | 525 | 175 | 342 | 249 | 319 | 119 | 249 | 298 |
### Explanation of the Table
#### Variables:
- **Size (sq. ft.) X**: This indicates the area of each property in square feet.
- **Asking Price Y ($)**: This represents the asking price for each corresponding property listed in thousands of dollars.
#### Data Insights:
- Properties with larger sizes generally tend to have higher asking prices, as observed from the data points.
- Example: A property with 3,408 sq. ft. has an asking price of $525K, whereas a property with 650 sq. ft. has an asking price of $119K.
### Graphical Representation:
To better understand the trends and relationship between property size and asking price, plotting this data on a scatter plot would be ideal. The Size (sq. ft.) would be on the X-axis, and the Asking Price ($) would be on the Y-axis. This visual aid helps in identifying any linear or non-linear relationships between the two variables.
#### Summary:
This table serves as a foundational dataset for examining how different factors like size influence property prices, making it a valuable resource for real estate market analysis.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F1e12f6b9-85e5-44e1-bab8-a3bff89a7e95%2Ffbf3eaf4-3631-4745-86a4-397a8e18f9a2%2Fapxz3w_processed.png&w=3840&q=75)
