Select the scenario which is an example of voluntary sampling. Answer Keypad Keyboard Shortcuts Tables An airline is interested in getting feedback about their on-board catering experience. They place a questionnaire in the pocket behind each airline seat for passengers to O fill out. An urban planner is interested in determining the traffic volume along a particular road. To estimate the traffic volume, he counts the number of cars that go by during the next 30 minutes. O To determine the mean domestic electricity consumption in the region, the electric company collects data from randomly selected households in the given region. A fitness center has 400 male clients and 300 female clients. They plan to buy new equipment, so they randomly select 80 male clients and 60 female clients and ask them what equipment they use the most.
Does the following dataset satisfy GARP?
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.
With Panel Data, if we assume that the individual effects vi are not correlated with the regressors Xit (i.e. E(vi|Xit) = 0), which one of the following statements is correct: The Fixed Effects estimator is not consistent. Both the OLS and the Random Effects estimators are not consistent. The OLS estimator is not consistent, but the Random Effects estimator is consistent. The OLS and the Random Effects estimator are consistent. All of the above. None of the above
The microstructure of an iron carbon alloy consists of proeutectoid ferrite and pearlite; the mass fractions of these microconstituents are 0.22 and 0.78, respectively. Determine the concentration of carbon in this alloy.
A researcher investigating whether government expenditure crowds out investment estimates a regression on data for 30 countries. I-investment; G-government recurrent expenditure; Y=gross domestic product; all measured in $US billion. P= population measured in million. Standard errors are in parentheses. Î= 18.10 (7.79) R² = 0.99 1.07G + 36Y (0.14) (0.02) She suspects that countries with higher GDP may have more variability in their investment. She sorts the observations by increasing size of gdp per capita (Y)and estimates the regression again for the 11 countries with the lowest gdp(Y)and the 11 countries with the largest gdp(Y). The RSS1 from the first regression is 7186. The RSS2 from the second regresison is 28101. Perform a Goldfeld-Quandt Test at a 5% significance level. a. The test statistic for this test is 0.256 b. The critical value defining the rejection region for Ho is 3.18 c. Is there heterscedasticity? Yes=1 or No-0. The answer is 0
A rectangle is a four-sided figure that has two sets of parallel sides, so that we have two sides of one length and two sides of another length; a square is just a special case of a rectangle in which all four sides are the same length. Therefore, the procedure for calculating area is the same no matter whether we are dealing with a rectangle or a square. The area of a rectangle is calculated as follows: Area = base x height = b × h In this formula, the base is the width of the rectangle and the height is simply how tall the rectangle Is. For example, if we have a rectangle that is 20 centimeters wide and 10 centimeters tall, its area can be calculated as follows: Area = 20 cm x 10 cm = 200 cm² Note the superscript '2' In our answer; this is because we have multiplied centimeters by centimeters. In economics, we are more likely to be dealing with quantities bought or sold and prices, so don't worry about it too much for our discussion. The area of a triangle A triangle is really just a…
The following relationships between wage (W) and education (EDU) are estimated using a sample of 100 individuals. Excel results are reported below Model 1: W=4.3-0.07 EDU+0.9 EDU2 ; se (4.9) (0.07) (0.03) SSR=0.74; SSE=22.7; SST=23.44; Model 2: W=894-21.96 EDU+0.6 EDU2-75.0 What2+6.5 What3; se (885) (25.54) (0.06) (85.0) (3.2) SSR=0.82; SSE=21.68; SST=22.50; where W is wage and What is the fitted value of W. 1. In Model 1 test the hypothesis that education has no effect on wage 2. Test the adequacy of model W=B1+B2 EDU+B3 EDU?
A cereal company checks the weight of its breakfast cereal by randomly checking 62 of the boxes. This particular brand is packed in 20-ounce boxes. Suppose that a particular random sample of 62 boxes results in a mean weight of 20.04 ounces. How often will the sample mean be this high, or higher if u = 20 and σ = 0.10 4
