(b) What is the p-value for the test? (Use technology to find the p-value. Round your answer to four decimal places.) p-value = 0.0719 (c) Suppose the sample standard deviation of serum creatinine in part (a) is 0.7 mg/dL. Assume that the standard deviation of serum creatinine is not known, and perform the hypothesis test in part (a). Report a p-value. Find the test statistic. (Round your answer to two decimal places.) 1.03 ✓ Use technology to report a p-value. (Round your answer to four decimal places.) p-value = 0.3233 State your conclusion. ⒸFail to reject Ho. There is insufficient evidence to conclude that the mean serum-creatinine level in this particular group of patients is different from that of the general population. O Reject Ho. There is insufficient evidence to conclude that the mean serum-creatinine level in this particular group of patients is different from that of the general population. O Reject Ho. There i sufficient evidence to conclude that the mean serum-creatinine level in this particular group of patients is different from that of the general population. O Fail to reject Ho. There is sufficient evidence to conclude that the mean serum-creatinine level in this particular group of patients is different from that of the general population. (d) Compute a two-sided 95% CI for the true mean serum-creatinine level (in mg/dL) in part (c). (Enter your answer using interval notation. Round your numerical values to two decimal places.)
