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=0.05, can the department’s claim be supported?a. No, since p of 0.037 is less than 0.05, fail to reject the null. Claim is alternative, so is not supportedb. Yes, since p of 0.037 is less than 0.05, reject the null. Claim is alternative, so is supportedc. No, since p of 0.037 is less than 0.05, reject the null. Claim is null, so is not supportedd. Yes, since p of 0.037 is less than 0.05, fail to reject the null. Claim is null, so is supported
