The following graph contains four lines (A, B, C and D), each of which has a slope that is either positive, negative, zero, or infinite.
For each of the following scenarios, indicate whether the relationship between the two variables is positive or negative, as well as which line on the previous graph has a slope that reflects this type of relationship.
Hint: The X-axis and Y-axis on the graph are not labeled intentionally. You need to substitute the variables from each scenario for the horizontal and vertical axis. For example, in the first scenario, X-axis should be labeled “ The average grade received" and Y-axis should be labeled "The number of hours spent studying".
Scenario: As the number of hours spent studying rises, the average grade received rises.
Relationship: Positive or Negative
Line: A, B, C, or D?
Scenario: As the number of hours spent watching TV rises, the average grade received falls.

- 1. Solve the following problem by using Excel for graph sketching. A soda vendor at Louisiana State University football games observes that more sodas are sold the warmer the temperature at game time is. Based on 32 home games covering five years, the vendor estimates the relationship between soda sales and temperature to be y = -240 + 8x, where y = the number of sodas she sells and .x = temperature in degrees Fahrenheit, (a) Interpret the estimated slope and intercept. Do the estimates make sense? Why, or why not? (b) On a day when the temperature at game time is forecast to be 80°F, predict how many sodas the vendor will sell. (c) Below what temperature are the predicted sales zero? (d) Sketch a graph of the estimated regression line.arrow_forwardWhen filing an income tax return, one can claim a deduction for charitable contributions. Let's simplify the income tax system and assume that the tax is proportional to the level of taxable income (income after deductions). (a) Suppose we increase the marginal income tax rate. An economic adviser claims that the effect of this tax change on the amount of charitable contributions is uncertain. Plot a simple graph that illustrates this situation (it involves the choice between charitable contributions and other spending), use it to explain why the effect is uncertain and explain what it depends on. (b) Now suppose that we instead increase the marginal tax rate but also provide a transfer that makes the bundle that used to be optimal before tax increased just affordable. According to the economic adviser this policy change will make people contribute more to charity.
