Problem Set #3J) The amount of income spent on housing is an important component of the cost of living. The totalcosts of housing for homeowners might include mortgages payments, property taxes, and utilitycosts (water, heat, electricity). An economist selected a sample of Inland Empire, California,homeowners and calculated housing costs as a percent of monthly income, 5 years ago and now.The information is reported below. Is it reasonable to conclude the percent is less now than 5years ago? Apply the 6-step hypothesis testing procedure to test using a = 5% (0.05).

xt:Bong-Cha is deciding what to do during the 30-minute break between her college classes. One rule she could follow is, "Choose the activity with the highest value" (A). Another rule she could follow is, "Choose the activity with the lowest opportunity cost" (B). Do you think Bong-Cha's choice if she follows rule (A) will be the same as the choice she would make if she followed rule (B)? [another way to think about it, "Is rule (A) identical to rule (B) in a sense that they would both induce the same choice?"].

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?

QUESTION 3 (Figure: US Business Cycle Expansions and Contractions) From the data on averages for all cycles we can conclude that over time: Business cycles data.pdf O The number of cycles during 1945-2020 exceeded the number of cycles during 1854-1919. The number of cycles during 1919-1945 exceeded the number of cycles during 1945-2020. The average duration of contractions during 1854-1919 was shorter than the average duration of contractions during 1945-2020. The average duration of expansions during 1854-1919 was shorter than the average duration of expansions during 1945-2020.
This question is intended to have a written response given. The writtenresponse should be 2-3 paragraphs maximum and focused on answer the specific questions of interest using the tools/concepts from lecture/tutorials. You may include agraph to support your argument/ideas, but this is not required (note: I would recommend you sketch a graph when thinking about how to answer this question, thoughthat does not need to be submitted). Leung and Seo wrote an article “How do government transfer payments affect retail prices and welfare? Evidence from SNAP” (Jan,2023) in the Journal of Public Economics. To answer this question, you do not need togo read the paper. I would in fact recommend against it as the paper is very technicaland assumes a knowledge of statistics that most students taking Econ 201 will nothave (some of the ideas will be discussed in Econ 233 and Econ 333). We will use theinformation/main ideas as a starting framework.In the United States, one of the largest welfare…

What is this equation used for? What do the variables mean? Can you give an example how a research study can be applied to this formula? Does it account for control variables ?
QUESTION 7 Which is NOT true about the coefficient of determination? As you add more variables, the R-square generally rises. As you add more variables, the adjusted R-square can fall. If the R-square is above 50%, the regression is considered significant. The R-square gives the percent of the variation in the dependent variable that is explained by the independent variables. The higher is the R-square, the better is the fit.
