#### Quiz 3: Regression Analysis

Q1. What does a regression analysis reveal to a marketer?

- The development of a brand architecture
- The potential budget options of various marketing ideas
- The value of a product
- The relationship between a number of variables

Q2. Zodiac wants to sponsor an up-and-coming golf player to endorse its watches. Using regression analysis to predict player earnings as a measure of success, they think player height and earnings might be related. Based on the graph above, what is the relationship between height and earnings–and what should Zodiac look for in a player to sponsor?

- Cannot be determined

- There is no relationship. With no discernible effect on earnings as height changes, Zodiac will need to consider other variables when selecting a player to sponsor.
- The relationship is positive, since earnings increase as height increases. Zodiac should look for a tall player to sponsor.
- The relationship is negative, since earnings decrease as height increases. Zodiac should look for a short player to sponsor.

Q3. Zodiac wants to sponsor an up-and-coming golf player to endorse its watches and is interpreting the data about height and earnings in the chart above. What should Zodiac expect the sign for the coefficient of height to be when they run a regression with earnings as the dependent variable and height as the independent variable?

- Negative – Earnings decrease as height increases
- Positive – Earnings increase as height increases
- Cannot tell the sign of a regression coefficient from the plot.

Q4. Based on the output from a regression of golf player heights and their corresponding earnings (above), what measure provides an estimate of the strength of the relationship between height and earnings?

- Coefficients
- T-statistic

- R-squared

Q5. Based on the output from a regression of golf player heights and their corresponding earnings (above), how much do earnings increase for each unit increase in height?

- 0.16
- -12.87
- 0.23
- 0.14

Q6. Based on the output from a regression of golf player heights and their corresponding earnings (above), how would you interpret the p-value of .01 for the coefficient of height?

- There is a 99% chance that a positive relationship between height and earnings WILL NOT be observed in another sample.
- There is 1% chance that a positive relationship between height and earnings WILL be observed in another sample.
- There is 1% chance that a relationship (positive or negative) between height and earnings WILL be observed in another sample.
- There is 99% chance that a positive relationship between height and earnings WILL be observed in another sample.
