Question 1 reset

The standard error of the mean decreases in direct proportion to sample size.

True

False

Question 2 reset

To perform a complete enumeration, one would need to examine every item in a population.

True

False

Question 3 reset

In everyday life, we see many examples of infinite populations of physical objects.

True

False

Question 4 reset

To obtain a theoretical sampling distribution, we consider all the samples of a given size.

True

False

Question 5 reset

Large samples are always a good idea because they decrease the standard error.

True

False

Question 6 reset

If the mean for a certain population were 15, it is likely that most of the samples we could take from that population would have means of 15.

True

False

Question 7 reset

The standard error of a sample statistic is the standard deviation of its sampling distribution.

True

False

Question 8 reset

Judgement sampling has the disadvantage that it may lose some representativeness of a sample.

True

False

Question 9 reset

The sampling fraction compares the size of a sample to the size of the population.

True

False

Question 10 reset

Any sampling distribution can be totally described by its mean and standard deviation.

True

False
