1. Statistics that are computed from sample information and used to estimate population parameters are called

a. Estimation point

b. Population sample

c. Standard Error of Estimate

2. Which of the following tables is used in the calculation of the estimate assuming a normal distribution follows?

a. Chi square table

b. F Table

c. Z Table

3. The consequence of not knowing the population standard deviation is that the Z table cannot be used in testing. What tables can be used for testing?

a. t Table

b. F Table

c. Binomial distribution table

4. The following are the characteristics of table t, except

a. Has a shape like a bell and is symmetrical

b. Can only be used if the sample is more than 30

c. Is a distribution that has a continuous pattern

5. The following are the characteristics of the point estimator, except:

a. Efficient

b. Consistent

c. Biased

6. An estimator is said ... if the time being estimated is close to the unknown population parameter when the sample size is getting bigger

a. Consistent

b. Unavailable

c. Efficient

7. The following are the factors that affect the size of the sample required in an average test, except:

a. The level of confidence you want

b. Acceptable margin of error

c. Population mean in a test
