The following data was experimentally obtained on the concentration (g/L) of albumin in two selected groups of
people:
Group I: 38.36, 39.61; 39.17, 38.82, 39.31, 38.82
Group II: 37.39, 37.47, 37.49, 37.47, 37.40; 37.46, 37.62
A two-tailed t-test (P=0.05) based on this data should lead to this conclusion regarding the mean albumin
concentrations in the two selected groups of people:
a. The two means do not differ significantly
b. Not enough data to draw a conclusion
c. The two means differ significantly
d. None of the above
answer is "C", please explain WHY!
