In the past, the mean gas mileage of a car is 32 mpg. The manufacturer has introduced a change in the production method and wants to perform a hypothesis test to determine whether the mean gas mileage has increased as a result. The hypotheses are
H0: μ = 32 mpg H1: μ > 32 mpg
Suppose that the actual average mileage has increased and the results of the sampling fail to lead to rejection of the null hypothesis.
Indicate which of the following is correct regarding this decision.

At one school, in 2005, the average amount of time that tenth-graders spent watching television each week was 21.6 hours. The principal introduced a campaign to encourage the students to watch less television. One year later, in 2006, the principal performed a hypothesis test to determine whether the average amount of time spent watching television per week had decreased. The hypotheses are: H0: μ ≥ 21.6 hours Ha: μ < 21.6 hours where μ is the mean amount of time,...

An automobile manufacturer claims that their car has a 56.7 miles/gallon (MPG) rating. An independent testing firm has been contracted to test the MPG for this car. After testing 14 cars they found a mean MPG of 56.6 with a standard deviation of 1.1. Is there sufficient evidence at the 0.1 level that the cars underperform the manufacturer's MPG rating? Assume the population distribution is approximately normal. Step 1 of 5: State the null and alternative hypotheses. Answer 2 Points...

An automobile manufacturer claims that its van has a 36.2 miles/gallon (MPG) rating. An independent testing firm has been contracted to test the MPG for this van since it is believed that the van has an incorrect manufacturer's MPG rating. After testing 220 vans, they found a mean MPG of 36.0. Assume the variance is known to be 4.41. A level of significance of 0.05 will be used. Make a decision to reject or fail to reject the null hypothesis...
