The primary metric for a project is reduced cost for process A .A consequential metric could be:

The primary metric for a project is reduced cost for process A . Baseline data might include:

According to the Central Limit Theorem:

The term “expected value” is closest to the term:

A random sample is selected from a population of measurements. The mean of the sample is not equal to the mean of the population. This is due to:

A population of size 1,000,000 has mean 42 and standard deviation 6. Sixty random samples, each of size 15 are selected. According to the Central Limit Theorem the distribution of the sixty sample means has a mean of approximately:

A population of size 1,000,000 has mean 42 and standard deviation 6. Sixty random samples, each of size 15 are selected. According to the Central Limit Theorem the distribution of the sixty sample means has a standard deviation of approximately:

A ____ from a sample is used to estimate a population _____. The two words that best fill these blanks are:

Deming called the technique of studying a sample to gain understanding of the distribution of a population an enumerative study. His main objection to these studies was:

If the probability that an event will occur is 0.83, then the probability that the event will not occur is:

If the probability that event A occurs is 0.51, the probability that event B occurs is 0.64 and that probability that both A and B occur is 0.23 then:

If the probability that event A occurs is .51, the probability that event B occurs is .64 and events A and B are statistically independent then:

A population is bimodal. One hundred samples of size 30 are randomly collected and the
100 sample means are calculated. The distribution of these sample means is:

A population is bimodal with a variance of 5.77. One hundred samples of size 30 are randomly collected and the 100 sample means are calculated. The standard deviation of these sample means is approximately:
