An F-statistic is:
| a. | the ratio of two variances |
| b. | a populationparameter          |
| c. | the variance of the difference between means |
| d. | a ratio of two means |
| e. | the difference of standard deviations |
The characteristics of the F-Distribution include allbut:
| a. | it is positively skewed |
| b. | it is symmetrical much like the normal distribution |
| c. | its value can never be negative |
| d. | there is a family of distributions dependent upon the degrees offreedom |
| e. | it is continuous |
Which statement about the F-distribution iscorrect:
| a. | it is the same as the t-distribution. |
| b. | It is always between -1 and +1. |
| c. | It is always between 0 and 1. |
| d. | It increases toward infinity as the degrees of freedomincrease. |
| e. | It cannot be negative. |
Analysis of Variance is used to:
| a. | compare nominal data. |
| b. | compare population proportions. |
| c. | simultaneously compare several population means. |
| d. | calculate an normal probability. |
| e. | compute the t test. |
