1: The binomial distribution depends on which of the following?

1. Mean and standard deviation
2. Sample size and probability of success
3. Standard deviation and number of successes
4. Mean and probability of success

2: The normal distribution depends on which of the following?

1. Mean and standard deviation
2. Sample size and probability of success
3. Standard deviation and number of successes
4. Mean and probability of success

3: In a normal distribution, 95% of observations are

1. within one standard deviation of the mean.
2. included in computing the mean.
3. within two standard deviations of the mean.
4. divided by the sample size to get the standard deviation.

4: A sampling distribution shows

1. the distribution of means from multiple samples.
2. the distribution of sample sizes over time.
3. the distribution of scores in the population.
4. the distribution of observations from a single sample.

5: The z-score is

1. the number of standard errors between the mean and some observation.
2. the difference between the sample mean and population mean.
3. the width of the 95% confidence interval.
4. the number of standard deviations an observation is from the mean.
