Question (not from textbook)
Studies are being conducted to test the effectiveness of kidney transplants in diabetes patients. Of interest
is the mean number of months that patients survive following the transplant. The following data (in
months):
Researcher A: 12, 56, 98, 14, 34, 23, 78, 64, 13, 27, 35, 108
Identify the (i) target population, (ii) variable of interest, (iii) parameter of interest, (iv) sample, (v)
sample size, and the (vi) sample statistic.
Answer:
I) Target population: All patients who suffer from diabetes and have undergone a kidney
transplant.
II) Variable of interest: Length of time in months that patients with diabetes survive
following a kidney transplant.
III) Parameter of interest: mean/average length of time in months that patients with diabetes
survive following a kidney transplant.
IV) Sample: 12 patients who suffer from diabetes and have undergone a kidney transplant.
V) Sample size: 12
VI) Sample statistic: sample mean/average length of time in months that patients with
diabetes survive following a kidney transplant.
A. The sample mean is 46.83 months.
