n a study of end-stage renal disease, the creatinine values were obtained for 12 end-stage renal patients undergoing hemodialysis. These creatinine values have a mean of 11.9 mg/dl and a standard deviation of 3.6 mg/dl. A nephrology nurse believes that the population mean creatinine is 8.4 mg/dl. Using the JMP ouput, what is the conclusion for the hypothesis test that tests the nurse's belief that the true population mean creatinine is 8.4 mg/dl?
