3. For a Normal probability distribution, a negative value of Z indicates that the Z value is to the ----------- of the mean.

4. A standard normal probability distribution is a normal distribution with a mean of ---------------, and a standard deviation of -------------.

5. The standard error is the difference between the value of the -------------mean, and the value of the --------------mean.

Explanation / Answer

Dear Student, only one question is allowed at a time.

1)

As the sample size increases, the standard error becomes smaller, other things being equal.
On the other hand, with smaller sample sizes, there is likely to be greater variability among the sample means because some will be much closer to the population mean than will others.
