Answer to Question 1

C

Answer to Question 2

Three factors are required to specify sample size:
(1) Variance, or heterogeneity, of the population - this refers to the standard deviation of the population. Only a small sample is required if the population is homogeneous. As heterogeneity increases, so must sample size.
(2) Magnitude of acceptable error, or the confidence interval - indicates how precise the estimate must be.
(3) Confidence level - typically use the 95 percent confidence level. This, however, is an arbitrary decision based on convention; there is nothing sacred about the 0.05 chance level.
