The mean serum-creatinine level measured in 14 patients 24 hours after they received a newly proposed antibiotic was 1.2 mg/dL. 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.) Ho: μ=1 H₁: |μ!= 1 Find the test statistic. (Round your answer to two decimal places.) 1.66 x 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 > 1.96 test statistic < -1.96 State your conclusion. 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. 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. 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.
