II. TRUE or FALSE. Write T if the statement is true, otherwise write F if the statement is false. Erasure
means wrong.

1. The estimator, the parameter, and the result of the estimator which is called an estimate are different from
each other.

2. The confidence interval is stated in terms of level of confidence.

3. All variables that are approximately normally distributed can be transformed to standard normal variables.

4. We can transform the whole normal curve into a standard normal curve if the mean is equal to 0.

5. A confidence interval estimate of 100% is desirable over an interval estimate of 90%.

6. The three confidence levels most commonly used are 90, 95, and 99%.

7. Interval estimates are preferred over point estimates since a confidence level can be specified.

8. If we wish to find various probabilities pertaining to where an arbitrary measurement may lie in a normal
distribution, it must first be transformed into standard normal.

9. Increasing the mean shifts the normal distribution to the left.

10. The left and right tails of the normal distribution extend indefinitely but come infinitely close to the x-
axis.
