The mean and standard deviation serum creatinine level measured in 12 patients, 24 hours after they received a newly proposed antibiotic, was 1.2 mg/dL and 0.6 mg/dL, respectively.You may assume that the levels follow a normal distribution.If the mean serum creatinine in the general population is 1.0 mg/dL, test if the mean serum creatinine level in this patient group is significantly different from that of the general population.Use a significance level of 0.05.Report the relevant p-value matching your alternative hypothesis and state your conclusion (i.e., reject or fail to reject the null hypothesis).
