A state Department of Transportation claims that the mean wait time for various services at its different location is more than 6 minutes. A random sample of 16 services at different locations has a mean wait time of 9.5 minutes and a standard deviation of 7.3 minutes. At α=0.01, can the department's claim be supported assuming the population is normally distributed?

Group of answer choices

No, since p of 0.037 is greater than 0.01, reject the null. Claim is null, so is not supported

Yes, since p of 0.037 is greater than 0.01, fail to reject the null. Claim is null, so is supported

Yes, since p of 0.037 is less than 0.07, reject the null. Claim is alternative, so is supported

No, since p of 0.037 is greater than 0.01, fail to reject the null. Claim is alternative, so is not supported
