(CO 5) A car company claims that the mean gas mileage for its luxury sedan is at least 24 miles per gallon. A random sample of 7 cars has a mean gas mileage of 23 miles per gallon and a standard deviation of 2.4 miles per gallon. At 0:0.05, can you support the company's claim assuming the population is normally distributed? 0 Yes, since the make is less than alpha, the null is rejected. The claim is the alternative, so is not supported 0 No, since the p-yaiue is greater than alpha, the null is not rejected. The claim is the altematiye, so is supported 0 No, since the p-Value is less than alpha, the null is rejected. The claim is the null, so is not supported 0 Yes, since the make is greater than alpha, the null is not rejected.

Claim is null, so is not supported 0 Yes, since p of 0.037 is less than 00?, reject the null. Claim is alternative, so is supported 0 No, since p of 0.03? is greater than 0.01 , fail to reject the null. Claim is alternative, so is not supported 0 Yes, since p of 0.03? is greater than 0.01, fail to reject the null. Claim is null, so is supported
