Hypotheses and Conclusions: According to the National Transportation Safety Board, the average SUV in 2020 gets approximately 32 mpg highway fuel economy. A small auto manufacturer in the US claims that their new line of SUVS averages more than 32 highway mpg. a) Which are the appropriate null and alternative hypotheses for this study? Ο H: μ 32 HẠ: H = 32 O Ho: H z 0 HA: H = 0 Ο H0: μ= 32 HA: µ > 32 Ο Hg: μ - 32 HA: µ < 32 b) Suppose that the result of the statistical test is to Fail to reject Ho. Which is the proper conclusion? O There is not enough information to answer this question. O The test has proved that the automaker's claim that their SUVS get better gas mileage. O There is not sufficient evidence to support the claim that the automaker's SUVS get better gas mileage. O There is sufficient evidence to support the claim that the automaker's SUVS get better gas mileage.
