1. The expected value of random variable is a measure of central location.

2. The variance of a random variable is a measure of variability.

3. Measures of variability give the degree of spread of the values.

4. The standard deviation is the square of the variance.

5. A standard normal distribution has a mean of 1 and a variance of 0.

6. The total area under the normal distribution curve is 1.

7. In a normal distribution, the mean, median, and the mode are equal.

8. The normal distribution is a distribution for continuous random variables.

9 The normal curve is symmetrical bell - shaped curve.

10. A sampling distribution is a probability distribution of a parameter.

11. Measures computed from sample data are called statistics.

12. Measures computed using population data are called parameters.

13. The mean of the sampling distribution of x is smaller than the mean of th
distribution of X.
