1. ___Estimator__ is the result of applying an estimator to a specific set of data. (3 points)

2. In regression model, ____________is the estimated change in the dependent variable associated with one unit change in the dependent variable. (3 points)

3. If the average value of an estimator equals the population parameter being estimated, the estimator is____________. (3 points)

4. The largest possible distance (= maximum allowed error) from the point estimate that a confidence interval will cover is called as a(an) ____________. (3 points)

5. ____________is a component of the criteria used to evaluate the hypothesis which is calculated from the sample data gathered. Usually, it is compared with critical value of , the level of the test. (3 points)

6. The director of research and development is testing a new drug. She wants to know if there is evidence at the 0.02 level that the drug stays in the system for less than 330 minutes. For a sample of 46 patients, the meantime the drug stayed in the system was 323 minutes. Assume the population variance is known to be 361.
