In the year 2000, the average vehicle had a fuel economy of 24.09 MPG. You are curious as to whether the average in the present day is greater than the historical value. The hypotheses for this scenario are as follows: Null Hypothesis: μ ≤ 24.09, Alternative Hypothesis: μ > 24.09. A random sample of 34 vehicles shows an average economy of 24.24 MPG with a standard deviation of 3.185 MPG. What is the test statistic and p-value for this test?

    In the year 2000, the average car had a fuel economy of 23.2 MPG. You are curious as to whether the average in the present day is less than the historical value. The hypotheses for this scenario are as follows: Null Hypothesis: μ ≥ 23.2, Alternative Hypothesis: μ < 23.2. If the true average fuel economy today is 38 MPG and the null hypothesis is not rejected, did a type I, type II, or no error occur? Question 13 options:...

    8. In a recent year the fuel economy of all passenger vehicles was 19.8 mpg. A trade organization sampled 50 passenger vehicles for fuel economy and obtained a sample mean of 20.1 mpg with standard deviation 2.45 mpg. The sample mean 20.1 exceeds 19.8, but perhaps the increase is only a result of sampling error. a. Perform the relevant test of hypotheses at the 20% level of significance using the critical value approach. b. C. Compute the observed significance of...

    (8 points) Fueleconomy.gov, the official US government source for fuel economy information, allows users to share gas mileage information on their vehicles. The histogram below shows the distribution of gas mileage in miles per gallon (MPG) from 14 users who drive a 2012 Toyota Prius. The sample mean is 53.3 MPG and the standard deviation is 5.2 MPG. Note that these data are user estimates and since the source data cannot be verified, the accuracy of these estimates are not...

    The fuel economy sticker on a new SUV’s window sticker indicates the owner can expect 16 mpg in city driving and 20 mpg highway driving and 18 mpg overall. Accurate gasoline records for one such vehicle were kept, and a random sample of mileage per tank of gasoline was collected: 17.6 17.7 18.1 22.0 17.0 19.4 18.9 17.4 21.0 19.2 18.3 19.1 20.7 16.7 19.4 18.2 18.4 17.1 17.4 15.8 17.9 18.0 16.3 17.5 17.3 20.4 19.1 21.0 18.1 19.0...

    It is reported in USA Today that the average flight cost nationwide is $507.93. You have never paid close to that amount and you want to perform a hypothesis test that the true average is actually greater than $507.93. The hypotheses for this situation are as follows: Null Hypothesis: μ ≤ 507.93, Alternative Hypothesis: μ > 507.93. A random sample of 27 flights shows an average cost of $501.435 with a standard deviation of $60.2994. What is the test statistic...

    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 41 vehicles owned by residents of Chicago showed that the average mileage driven last year was 10.9 thousand miles. Does this indicate that the average miles driven per vehicle in Chicago is different from (higher or lower than) the national average? Use a 0.05 level of significance. What are we testing in this problem?...
