Question

A group of researchers conducted a small study where they collected blood samples to determine the concentration of C-reactive proteins, an inflammatory marker, from 37 individuals. Assuming the researchers know that the mean value for the C-reactive protein concentration in the population as a whole is 1.5 mg/dl and the standard deviation for CRP concentrations is 0.5 mg/dl, the z score for the probability that the researchers would obtain a mean of 1.67 for the sample population is approximately 2.07.
