D) 16

Solution

1.

One way analysis of variance(ANOVA) is used with data categorized with one treatment.

3. The variance between samples is an estimate of the common population variance s2 that is based on the variability of sample means the variability among the sample means.

4.

The procedures for testing hypotheses with contingency tables with two rows and two columns (2 x 2) have the requirement that every cell must have an expected frequency of more than 5.
