An analyst for a shopping district would like to determine the rent that should be charged for retail spaces depending on how close they are to paning. That is, they would like to determine the rent to charge, using aistance from parning. The analyst takes a random sampie of retail spaces in similer shopping districts and measures the monthly rent (5) and distance from parking (in yards) for each retail space. 4) What are the dependent and independent variables in this analysist

Question

Can I use 8 questions and have all 8 completed, thank you.

4. Write down the Estimated Regression Equation (ERE).
5. What is the predicted rent for retail spaces that are 30 yards from parking? What is the predicted rent
for retail spaces that are 175 yards from parking? Interpret both of these predicted values in words.
6. Graph the two points you calculated in a3 on the scatterplot above. If you can't print it out, just draw
the axes, approximate the dots, and draw your line through the two points. Use a straight edge to draw
the regression fine through the two points.
7. Interpret the sample slope, b, in words
8. The lower and upper bounds of the 93% confidence interval for the population silope , are reported
in the Distance row of the output in the Lower 95% and Upper 95% columns, respectively. So, the 93%
confidence interval for the population slope f is (-14.47, -837). Interpret this interval in words.

An analyst for a shopping district would like to determine the rent that should be charged for retail
spaces depending on how close they are to parking That is, they would like to determine the rent to
charge, using distance from parking. The analyst takes a random sample of retail spaces in similar
shopping districts and messures the monthly rent (5) and distance from parking (in yards) for each retail
space
1) what are the dependent and independent variables in this analysis?

2. Do you anticipate that the regression line will have a positive or a negative slope? Why:
Here is the Coefficients Table from the regression output (See the Regression Output Equations
