Researchers conducted an observational study of automobile drivers and their cell phone use by manually observing traffic in heavily congested areas. They would record the amount of time they observed individual drivers on the phone while operating their vehicle in stop and go traffic and the number of accidents on a particular section of highway over the course of a month. The accompanying graph depict the data they recorded, each point represents a 1 mile section of heavily congested roads. From the data, which of these is a potentially valid conclusion? Cell-phone use while driving increases the rate of accidents. O Car accidents and cell-phone use have no relationship. The increasing rate of car accidents causes increased phone-call length. A conclusion cannot be made; the data ignores the omitted variable of which cell-phone provider each person uses. If the x and y variables were swapped, what would the new slope be? zero positive Number of car accidents 10- 9- 8- 7- 5- 4- 3- 2-…
A finance manager employed by an automobile dealership believes that the number of cars sold in his local market can be predicted by the interest rate charged for a loan. Interest Rate (%) Number of Cars Sold (100s) 3 5 10 7 8 2 The finance manager performed a regression analysis of the number of cars sold and interest rates using the sample of data above. Shown below is a portion of the regression output. Regression Statistics Multiple R0.998868 R2 0.997738 Coefficient |14.88462 Interest Rate -1.61538 Intercept 1. Are there factors other than interest rate charged for a loan that the finance manager should consider in predicting future car sales? 2. Is interest rate charged for a loan the most important factor to be considered in predicting future car sales? Explain your reasoning.The dealership's vice- president of marketing has requested a sales forecast at the prevailing interest rate of 7%. 3. As finance manager, what reasons would you convey to the vice-president in recommending…
T or F A household is frequently used in analyses because more consistent data are usually collected at that level.
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.
When considering data metrics, the first task is to define just what we want to occur and what we need to measure. True False
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

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.
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…
