Full Test Sampling Distributions Quiz Unit 8: Lesson 3 SCCA

Step-by-step explanation:

1. B. mean, variance, proportion

2. D. variance, mean, proportion

3. A. proportion

4. A. The sampling distribution of the variance requires repeating this process with the same sample several times. So this does not compare to the sampling distribution of the variance.

5. C. This is just one sample. The sampling distribution of the mean requires repeating this process with the same sample several times.

6. B. No, the sampling distribution of the proportion is the distribution of the proportions from all samples, not just one.

7. A. (question: you randomly survey 25 people at a time) not a normal distribution

8. A (question: samples of size n=20) normal distribution skewed to the right.

9. B. (question: sample of size n=4000) normal distribution.

10. C. (question: You roll a die 8 times) not a normal distribution.

sample answer: you can determine whether each element of the domain is paired with exactly one element of the range. for example, if given a graph, you could use the vertical line test; if a vertical line intersects the graph more than once, then the relation that the graph represents is not a function.
