probably should be rejected
4___ Interaction occurs whenever the effects of one factor are
consistent.
consistent for all values of the second factor.
not consistent.
not consistent for all values of the second factor.
5___ Given that the null hypothesis for interaction has been rejected, the corresponding graph of this interaction should contain two or more _________________ lines.

dissimilar
nonparallel
intersecting
6___ The chisquare test is designed for use when observations are classified according to
frequencies.
magnitude.
numerical value.
categories.
7___ In the one-variable chi-square test, the null hypothesis makes a statement about two or more population proportions. If the null hypothesis specifies that voters are equally likely to prefer three political candidates for governor, each hypothesized population proportion will equal

8____ The null hypothesis is false if two or more population proportions differ
from each other.
appreciably from each other.
from the corresponding hypothesized proportions.
appreciably from the corresponding hypothesized proportions.
Explanation / Answer
