Suppose that you want to estimate the number of miles driven per year among all drivers living in Vermont and how the number of miles driven is related to a driver’s age. Suppose that you obtain a list of all drivers licensed by the State of Vermont, then take a simple random sample of 1000 drivers from the list and ask them to complete a survey regarding their driving habits during the last year and their age. A total of 620 people complete the survey.

  1. Identify the population, sampling frame, sample, and sample size.
  2. List two ways that sampling bias may have been introduced.
  3. Would you consider this to be a cross-sectional study or a longitudinal study? Explain your reasoning.

Miles driven by millennials. In 2009, the number of miles driven per year by persons aged 16–34 was 7,900. Assume that the number of miles driven was decreasing by 300 miles per year. a. Model this information with a linear equation. b. Use this model to predict how many miles persons aged 16–34 will drive per year in 2019. c. Explain why this model would not be expected to hold in 2030.

Suppose that you want to estimate the mean time it takes drivers to react following the application of brakes by the driver in front of them. You take a sample of reaction time measurements and compute their mean to be 2.5 seconds and their standard deviation to be 0.4 seconds. For each of the following sampling scenarios, determine which test statistic is appropriate to use when making inference statements about the population mean. Sampling Scenario Z t could use either...

Suppose you want to estimate the average mpg for cars being driven from campus to the Brass Rail. You sample a few of cars. The average mpg in your sample is 22, and the standard deviation is 10. If you want the error of the confidence interval to be no greater than 0.3 and to be 90% likely to contain the true population mean, how many cars should you randomly sample? Group of answer choices A)about 3,007 cars B)about 9,112...

It is necessary for an automobile producer to estimate the number of miles per gallon (mpg) achieved by its cars. Suppose that the sample mean for a random sample of 5050 cars is 30.630.6 mpg and assume the standard deviation is 3.63.6 mpg. Now suppose the car producer wants to test the hypothesis that μμ, the mean number of miles per gallon, is 31.631.6 against the alternative hypothesis that it is not 31.631.6. Conduct a test using a significance level...

Suppose that you are interested in estimating the average number of miles per gallon of gasoline your car can get. You calculate the miles per gallon for each of the next twenty-five times you fill the tank. Suppose that in truth, the values for your car are bell-shaped, with a mean of 20 miles per gallon and a standard deviation of 1. Find the possible sample means you are likely to get based on your sample of twenty-five observations. Consider...

the average annual miles driven per vehicle in the United States is 11.1 thousand miles, with σ ≈ 600 miles. Suppose that a random sample of 36 vehicles owned by residents of Chicago showed that the average mileage driven last year was 10.8 thousand miles. Does this indicate that the average miles driven per vehicle in Chicago is different from the national average? Use a 5% level of significance. a. State the null and alternative hypotheses ?0: ?1: b.What calculator...

Suppose you want to study the effects of the number of students per classroom in algebra courses and students’ performance in algebra courses for high schools in Kansas. You collected a random sample and now you have data for the above two variables. You called them as number students (which refers to the number of students per classroom in algebra courses), and students performance (which refers to the students’ performance in algebra courses - measured as their final grade in...
