3) You want to study the effects of disposable income, anti-smoking advertising and cigarette prices on the per capita consumption of cigarettes in US. You collect data on these variables across the 51 states over 20 years. You thus have 51x20=1,020 data points. For each state and year, you measure: Y=per capita consumption of cigarette (the fraction of the state population that smoked in that year); X1=per capital income in the state (in US$); X2=total expenditure in anti-smoking advertising in that state (in USS); and X3=average cigarette price in the state (in US$). You can then run a model: Y = Bo+Bi*X1+ B2*X+ B3* X3+ɛ Explain how you would test that the model is useful in predicting Y: How you would test the alternative hypothesis that you have at least one of the coefficients B1, B2 or ß3 is different from zero. (That is, the null is that all three coefficients are zero.) Use a significance level a=0.05.

Economic development is not only quantitative changes when it comes to the economic position of the country, but also qualitative changes (changing the economic structure, the emergence of new sectors and industries, new jobs, etc..). They lead to a better and more complete satisfaction of all human needs. Production per capita is a measure of the ability of a society to achieve their goals of social and economic development, all in order to meet the constantly growing social needs. The increase in output per capita in economic theory is expressed as economic growth, without which no economic development, but does not have…

Scenario: The following model was fitted to data on gas mileage as a function of weight of vehicle and type of vehicle (sport utility vehicle, family sedan, subcompact). Model: MPG = 50 - 0.004WT - 8SUV - 3FS MPG =miles per gallon; WT=weight of vehicle; SUV=sport utility vehicle; FS=family sedan Answer the questions below. 1. Each pound of weight reduces fuel economy by MPG 2. Fuel economy is reduced by MPG for a sport utility vehicle 3. Fuel economy is reduced by MPG for a family sedan 4. For a subcompact car weighing 1000 pounds, what is the predicted fuel economy?

6) Suppose you have the following data on the price of orange and the quantity sold: Price per Pound (in Quantity Sold (in Dollars) Pounds) 0.50 0.75 1.00 1.25 1.50 10 7 699 5 2 Assume that the quantity sold (Y) is a linear function of the price (X), i.e. Y₁ =B₁ + B₂X₁ + ε₁ Estimate the population regression coefficients.

The next 3 questions refer to the following: A housecleaning company receives 36 for each house cleaned. The tab below gives the relation between the number of workers and the number houses that can be cleaned per week. [[[[ Number of], [Workers]], [[Houses], [Cleaned]]], [0, 0], [1, 9], [2, 17], [3, 24], [4, 30], [5, 35], [6,36]] The marginal revenue from the fourth worker is If the company want to maximize profit and hires three workers, the wa rate of a house - cleaner can be no more than If the wage rate of a house - cleaner is 140, the maximum amount of pr the company can earn is

Statistics Denmark monitors the development of economic variables and measures e.g. productivity development.In general, it is one of the laws of economics that employee productivity determines the ability of employers to pay employees wages. The higher the productivity (per capita output), the higher the wages that can be paid. In a recession, such as Covid, companies are generally reducing their use of labor. The latest statistics show the following: In the third quarter of 2020, labor productivity growth in Denmark was 2%. This increase alone does not say much, but is considered to be able to reflect an increase in productivity following a contraction in labor input.   a. Show the relationship between production and labor use in the short term and at the same time explain with a picture what can cause the growth of productivity. b. What is happening to marginal production at the same time? c. Show how wages develop if companies keep marginal costs fixed in the above circumstances…

T or F  A household is frequently used in analyses because more consistent data are usually collected at that level.

the unemployment rate for 18- to 34-year-olds was reported to be 10.8% (the Cincinnati Enquirer, november 6, 2012). assume that this report was based on a random sample of four hundred 18- to 34-year-olds. a. a political campaign manager wants to know if the sample results can be used to conclude that the unemployment rate for 18- to 34-years-olds is significantly higher than the unemployment rate for all adults. according to the bureau of labor Statistics, the unemployment rate for all adults was 7.9%. develop a hypothesis test that can be used to see if the conclusion that the unemployment rate is higher for 18- to 34-year-olds can be supported.b. use the sample data collected for the 18- to 34-year-olds to compute the p-value for the hypothesis test in part (a). using a 5 .05, what is your conclusion?c. explain to the campaign manager what can be said about the observed level of significance for the hypothesis testing results using the p-value
