The manufacturer claims that your new car gets 28 mpg on the highway. You suspect that the mpg is adifferent number for your car. The 54 trips on the highway that you took averaged 29.2 mpg and the standarddeviation for these 54 trips was 6.8 mpg. What can be concluded at the a = 0.10 level of significance?a. For this study, we should useSelect an answerb. The null and alternative hypotheses would be:Но:?Select an answerH1:?Select an answerc.
