MY NOTES Renal Disease ASK YOUR TEACHER The mean serum-creatinine level measured in 15 patients 24 hours after they received a newly proposed antibiotic was 1.1 mg/dL. Ho: You can use SALT, to answer parts of this question. (a) If the mean and standard deviation of serum creatinine in the general population are 1.0 and 0.4 mg/dL, respectively, then, using a significance level of 0.05, test whether the mean serum-creatinine level in this group is different from that of the general population. State the null and alternative hypotheses (in mg/dL). (Enter != for # as needed.) H₁: PRACTICE ANOTHER H=1.0 U>1.0 X X X Find the test statistic. (Round your answer to two decimal places.) 0.97 ✔ Find the rejection region. (Round your answers to two decimal places. If the test is one-sided, enter NONE for the unused region.) test statistic > 0.05 test statistic < NONE State your conclusion. 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. 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 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 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. (b) What is the p-value for the test? (Use technology to find the p-value. Round your answer to four decimal places.)
