[B]The variation of the sample mean from the population mean becomes smaller
[C]The variance of the sample becomes less than the variance of the population

6. The sampling distribution of the mean is a distribution of
[A]Means of individual populations
[B]Observations within a population
[C]Observations within a sample

7. When estimating the population mean from a sample taken from a normal population with unknown variance, the t distribution may be used with number of degrees of freedom equal to
[A]Sample size
[B]Sample size + 1
[C]Sample size – 1

8. Which type of sampling is appropriate when the population consists of well-defined groups such that the elements within each group are heterogeneous and each group is a representative of the population as a whole?
[A]Simple random sampling
[B]Cluster sampling
[C]Stratified sampling
[D]Systematic sampling

9. If a hypothesis is tested at a significance level of 10% then it means that
[A]There is a 10% probability that the null hypothesis will be rejected though it is true
[B]There is a 10% probability that the null hypothesis will be false
[C]There is a 10% probability that the null hypothesis will be true

[C]If the slope of a regression equation is positive, then the coefficient of correlation between the variables involved is negative
[D]If the slope of a regression equation is negative, then the dependent variable decreases as the independent variable decreases

[A]Mean value of Y when X = 0
[B]Change in mean value of Y per unit change in X
[C]True value of Y for a fixed value of X
