If the size of sample equals the size of the population, we would not expect any error in estimating the population parameter.
An estimate of the population mean based upon a large sample is less reliable than an estimate made using a small sample.

To evaluate the effect of a treatment, a sample of n = 16 isd from a population with a mean of µ = 42, and the treatment is administered to the individuals in the sample. After treatment, the sample mean is found to be M = 35.
A researcher conducts independent-measures study comparing two treatments as well as reports the t statistic as t(28) = 2.039.
Employ the value of the linear correlation coefficient r to determine the coefficient of determination and the percentage of the total variation that can be explained by the linear relationship between the two variables. R=0.1
Assume IQ scores were obtained from randomly chosen sibling. For 20 such pairs of people, the linear correlation is 0.917 and equation of the regression line is y=6.44+0.94x, where x shows IQ score of the younger child.
