A researcher is interested in finding out the factors which determined the yearly spending on family outings last year (Y, measured in dollars). She compiles data on the number of members in afamily (X1), the annual income of the family (X2), and the number of times the family went out on an outing in the last year (X3). She collects data from 313 families and estimates the followingregression:ŷ=120.45+1.12X₁ +1.05X2 +1.05X3.Suppose B1, B2, B3, denote the population slope coefficients of X1, X2, and X3, respectively.The researcher wants to check if neither X₁ nor X2 have a significant effect on Y or at least one of them has a significant effect, keeping X3 constant. She calculates the value of the F-statistic for thetest with the two restrictions (Ho: B₁ = 0, ß₂ = 0 vs. H₁: B₁ #0 and/or ß2 0) to be 4.61.The p-value for the test will be(Round your answer to two decimal places.)At the 5% significance level, we willthe null hypothesis.QUESTION NUMBER 9

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?
For the students of the college, the visual appearance of the campus is _______(rival/nonrival) and ______(nonexcludable/excludable). Thus, the visual appearance would be classified as a public good. Suppose the college administrators estimate that the beautification initiative will cost $34,980. To decide whether the initiative should be undertaken, administrators conduct a survey of the college's 1,460 students, asking each of them their willingness to pay for the beautification project. The average willingness to pay, as revealed by the survey, is $32. The benefit of the beautification initiative, as suggested by the survey, is $_______. Because the estimated benefit is _______(less/greater) than the cost, the college administrators _______(should not/should) undertake the beautification initiative. The calculation of the benefit of the beautification initiative relied on the ability of the administrators to capture the true willingness to pay of each student accurately. Which…

Many investors and financial analysts believe the Dow Jones Industrial Average (DJIA) gives a good barometer of the overall stock market. On January 31, 2006, 9 of the 30 stocks making up the DJIA increased in price (The Wall Street Journal, February 1, 2006). On the basis of this fact, a financial analyst claims we can assume that 30% of the stocks traded on the New York Stock Exchange (NYSE) went up the same day.A sample of 70 stocks traded on the NYSE that day showed that 31 went up.You are conducting a study to see if the proportion of stocks that went up is is significantly more than 0.3. You use a significance level of α=0.002α=0.002.What is the test statistic for this sample? (Report answer accurate to three decimal places.)test statistic = What is the p-value for this sample? (Report answer accurate to four decimal places.)p-value = The p-value is... less than (or equal to) αα greater than αα This test statistic leads to a decision to... reject the null accept the null…
The Xhang Corporation operates five clothing suppliers in China to provide merchandise for Nike. Nike recently sought information from the five plants. One variable for which data was collected was the total money (in U.S. Dollars) the company spent on medical support for its employees in the first three months of the year. Data on number of employees at the plants are shown. These data are as follows: Medical $7,400 $14,400 $12,300 $6,200 $3,100 Employees 123 402 256 109 67 (a). Compute the weighted mean medical payment for these five plants using number of employees as the weights. (b). Explain why Nike would desire that a weighted be computed in this situation rather than a simple numeric average Answer all questions
Many of the survey questions focus on the used to pay for college, so the undergraduates in the sur ing for their parents. For example, each participant is asked to report how much of the parent's current income is used to pay for college. Do you think it is wise to combine responses across the parents and undergraduates? Are you fully aware of how much money your parents are spending and borrowing for college? The authors report overall averages and percents in their repon spond. Chapter 6 Introduction to Inference 350 We will also consider this a sample from one population but this is debatable certainly Average college savings fund contribution. One survey question asked ho much money from a college savings fund, such as a 529 plan, is used to pay an answer Nonresponse should ahways be considered as a source of bias. In this case, the nonresponse is very low, so we'll proceed by treating the n1593 sample as EXAMPLE 6.4 for college. Of the 1600 who were surveyed, n= 1593 provided a…
