Provide an appropriate response. Test the claim about the population mean u at the level of significance a. Assume the population is normally distributed. Claim: u = 35; a = 0.05; o = 2.7 Sample statistics: x = 34.1, n = 35 Not enough information to decide. Reject Ho. There is enough evidence at the 5% level of significance to support the claim. Fail to reject Ho. There is not enough evidence at the 5% level of significance to support...
