- I'm unsure about the two Ps in the final part of the answer. Are those both the same variable? It seemed unclear to me how and why that happened. Can you help with that really quickly?arrow_forwardAn example of the interaction term between two independent, continuous variables is: a. Yi = B0 + B1Xi+ B2DI + B3(Xi× Di) + ui. b. Yi = BO + B1X1¡+ B2X21+ ui. c. Yi = B0 + B1D1¡+ B2D2I+ B3 (D1i× D2i) + ui. d. Yi = B0 + B1X1¡ + B2X21+ B3(X1i× D21) + ui. e.All of the above. f. None of the above.arrow_forwardThe goal of the consumer is to maximize the total utility or satisfaction derived from their purchase choices, given the unique budget constraint. To calculate total utility of a given combination of T- shirts and movies, one would use the following approach: Group of answer choices Use utils as a measure of utility, assigning a specific number to T-shirts and movies, and then add those together. For a given combination of T-shirts and movies, survey a group of individuals to determine an average for utils to be assigned to the number of T-shirts and movies. For a given combination of T-shirts and movies, assign a number of utils to that combination. For a given combination of T-shirts and movies, use Google to identify the number of utils associated with the number of T-shirts and movies and then sum them.arrow_forward
- An increase in meat prices coincides with an increase in rainfall is an associative relationship the statement above is true/false?arrow_forwardChildren who were breastfed as infants have higher average IQs on average than children who were not. Breastfeeding advocates claim that this is due to the superior nutrition in breastmilk including brain building chemicals such as DHA. You have been hired to investigate this relationship more fully. Your employers are worried about the possibility of omitted variables biasing the results of the study. Name 3 possible omitted variables and explain how they might bias the results. Explain 2 empirical strategies you might use in your investigation.arrow_forwardThe presence of Heteroscedasticity can be investigated by using... .arrow_forward
- (a) Rank the three economic variables from most important to least important.Provide one relevant reason to justify your selection for each of the threepositions.arrow_forwardContext : The London Metro Bus is crowded for travel during peak hours. During such travel hours two daily passengers ‘James’ and ‘Robert’ enter the Metro. Luckily, two adjacent seats are free in the bus. Each of them must decide whether to sit or stand. For both, sitting alone is more comfortable than sitting next to the other person, which in turn is more comfortable than standing. Question : Assume that both ‘James’ and ‘Robert’ are altruistic, ranking outcomes according to the other person’s comfort and, out of politeness, prefer to stand than to sit if the other person stands. Model the situation as a strategic game and find any Nash equilibrium (equilibria) if it exists. Does a dominant strategy exist for either ‘James’ or ‘Robert’ with these preferences? show ALL steps and working in support to your answerarrow_forwardwhat is correlation cofficientarrow_forward
- What is the difference between univariate and multivariate analysis? Give an example for when a univariate analysis might be used and an example of when we use multivariate analysis.arrow_forwardA kids' organization sold 570 bars last year at $ 2.55 per candy bar. Research has suggested that for each $ 0.25 price increase, they will sell 20 less candy bars. They want to know what price should they sell their candy bars at to maximize their revenue. Please help them out, showing your work neatly in the following steps. And please label the steps clearly with the letters A through F A) Define your variables. This means that for every letter you use to represent a value, you communicate what it equals in words. B) Find the linear equation that relates the price and the number sold. C) Determine a function that represents the Revenue. (Remember, Revenue = (Price)*(Number Sold)). D) Graph your revenue function on your calculator or Desmos or something similar and on your paper, labeling the axes and the maximum point. E) Uusing your calculator or Desmos or something similar, use your graph to determine the price that maximizes the revenue for the organization. Do NOT use calculus…arrow_forwardIs there any graph that can support this answer?arrow_forward
