A car manufacturer claims that its latest model can average 60 miles per gallon on the highway - and an auto magazine's editor wants to put that claim to the test. (a) Write the null hypothesis for this situation. (b) Write the alternate hypothesis, if the editor wants to prove that the actual miles per gallon is lower than what's being claimed. (c) Write the alternate hypothesis, if the editor wants to prove that the actual miles per gallon is simply different from what's being claimed.

Alex hypothesized that students study less than the recommended two hours per credit hour each week outside of class. Alex performed a hypothesis test and told a colleague that he had evidence to indicate his hypothesis was true. Which of the following is a true statement that his colleague could have said? Choose the correct answer below OA. Alex might have made a Type I Error. B. There was no chance Alex could have made any error. OC. Alex might have made a Type Il Error OD. Alex should never accept the null hypothesis as true
The Null hypothesis, denoted by H0,represents the hypothesis that will be accepted only if the data provide convincing evidence of its truth.truefalse
A media personality argues that global temperatures are not rising, because every year an increase is reported, such as 0.09 degrees C. The difference from the previous year is less than the margin of error of about 0.13 degrees C, so that difference should be ignored. What is a strong counter argument? The difference is only 0.4 but that is still a significant change. The change of 0.9 is not a lot and thus should be ignored. The margin of error is larger than the increase so we should consider it an issue just extra information and thus can be ignored. The margin of error is quite small compared to the change year over year, so it is a significant issue.
A social psychology professor is interested in determining whether cell phone use while driving is related to having received a speeding violation. Complete the following. What statistical test would be appropriate to use? Explain the rationale for your answer. Suggest how levels of these variables might be arranged in a table. Write an example of how the null and alternative hypotheses for this test could be stated. Is the statistical test right-tailed, left-tailed or two-tailed? Explain the rationale for your answer. Assuming a statistically significant outcome, write a statement summarizing the conclusion.
A media personality argues that global temperature are not rising, because every year an increase is reported such as 0.08 degrees C. The difference from the previous year is less than the margin of error of about 0.15 degrees C. So that difference should be ignored. What is a strong counter argument?
