Consider the figure below that shows the relationship between advertising expenditure (on the x-axis) and sales revenue (on the y-axis). Which one of the following statements is TRUE? Sales Revenue 3000 2500 2000 1500 1000 500 0 0 20 Ad Dollars vs Sales Revenue 40 60 80 Ad Dollars Spent 100 120 ● 140 A linear model overpredicts sales revenue at lower levels of advertisement expenses. The R2 value with a linear specification will be higher than that with a quadratic specification. With a quadratic specification, we find an increasing marginal productivity of advertisement. With a liner specification, we find an increasing marginal productivity of advertisement.

The data for this question is given in the file 1.Q1.xlsx(see image) and it refers to data for some cities X1 = total overall reported crime rate per 1 million residents X3 = annual police funding in $/resident X7 = % of people 25 years+ with at least 4 years of college (a) Estimate a regression with X1 as the dependent variable and X3 and X7 as the independent variables. (b) Will additional education help to reduce total overall crime (lead to a statistically significant reduction in crime)? Please explain. (c) Will an increase in funding for the police departments help reduce total overall crime (lead to a statistically significant reduction in total overall crime)? Please explain. (d) If you were asked to recommend a policy to reduce crime, then, based only on the above regression results, would you choose to invest in education (local schools) or in additional funding for the police? Please explain.
Please no written by hand solution a) Suppose in a regression of weekly salaries on years of schooling for males(m) and females(f), the following results are obtained. Wm = 50Sm and Wf = 40Sf. where Wm (Wf) denotes weekly salary and Sm (Sf) denotes years of schooling for males and females respectively. 50 and 40 are the coefficients on schooling in the male and female regression respectively. On average, men have 12 years of schooling and women have 10 years of schooling. What is the average male-female wage differential? Is this a good estimate of discrimination? Explain why/why not. Using the information in the question, what would you propose as a better estimate of discrimination? State any assumptions that you use and explain your answer.
Using Excel, Big Poppa's estimates the weekly demand function for its BBQ sandwiches to be QD = 1,385.63 - 22.30P. In reference to the estimated slope coefficient for price, which of the following standard errors gives you the most confidence (i.e., largest t-statistics) that the estimated slope coefficient is close to the true slope coefficient? 37) _____ A) -22.0 B) 2.15 C) 1.12 D) 22.0 Could you put some explanations please.
Imagine you are trying to explain the effect of square footage on home sale prices in the United States. You collect a random sample of 100,000 homes that recently sold. a) Homes can be one of three types: single-family houses, townhomes, or condos. How would you control for a home’s type in a regression model? b) Write down a regression model that includes controls for home type, square footage, and number of bedrooms. c) How would you interpret the estimated coefficients for each of the variables from part b? Be specific. Note Don't forget to include dummy variables.
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 “ ice-cream" and Y-axis should be labeled "The temperature". Relationship options: positive, negative Line options: A, B, C, D True or False: Line D has a slope of infinity.
General Cereals is using a regression model to estimate the demand for Tweetie Sweeties, a whistle-shaped, sugar-coated breakfast cereal for children.
