How do you find the p-values of (b.) and (c.)?? As well as how to find (d.)??

(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.)

Use technology to report a p-value. (Round your answer to four decimal places.)
p-value =
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.

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.
(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.)

Renal Disease
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.)
