For the problem in the picture I don't expect you to do the whole thing. If you could just state the null hypothesis and the alternate hypothesis that would be great
when talking about the hypothesis for this question, what would be the null and what would be the alternative
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.

For each problem, complete the following steps: Sarah, a university junior, chose to live on the honors floor of her dorm because she was told that the girls on that floor would be quiet and studious. In fact, Sarah was told that students on the honors floor study at least 11 hours per week. After living on the honors floor for a few months, Sarah is convinced that the students around her study less than 11 hours a week. To test her claim, Sarah polls 10 girls on her floor regarding the number of hours per week that they spend studying. Use the results listed in the table below to test Sarah’s claim at the 0.10 level of significance. Assume that the population distribution is approximately normal. 12 4 14 9 8 6 10 12 11 9arrow_forward
