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.

Expert Solution
Step 1

As per the Bartleby guildlines we have to solve first three subparts and rest can be reposted....

 

Given that

Sample size=15

Sample mean=1.1

Population mean=1

Population Standard deviation =0.4

We have to find

a... Hypothesis testing .

b..p value 

c..test statistic if population standard deviation is unknown and sample standard deviation =0.7

P value..
