(2 Points) describe the two purposes of using a regression analysis in the business decisions. 2. (2 points) what can you measure if you use a regression analysis? a. Pattern b. Trend c. Seasonality d. Irregularity 3. (2 points) take a look at number 1. Interpret 0.5607 (Do not simply say it is a measure of how close the data are to a regression line, and focus on the number) 4. (2 points) take a look at number 2. What does 15 mean in the table?Explanation / Answer
1)
To how dependent variable is influced by independent variables and get a regression equation
Predict the value of the Y varaible based on the known independent variables
2) We can measure patterns of variation using the regression analysis
3)
This is R square value , this means that the model is able to explain 56.07% variation in the data
4) 15 means that while building the regression model , we used 15 records/observations/number of rows
5) It is just an independent variable, no information given
6)
Slope is 205896 , this means for every unit increase in the value of X the value of Y increases by 205896 units
Please note that we can naswer only 4 subparts of a question at a time , as per the answering guidelines
