1True False The homogeneity of variance assumption requires

1.True False  The homogeneity of variance assumption requires that the two samples have equal variances.

2.True False  The independent groups t-test requires that the dependent variable be nominal data.

3.True False  The independent groups t-test measures whether two means are sufficiently different, given the amount of variation in the data.

4.True False  The normality assumption in an independent groups t-test requires that the degrees of freedom be large enough that the t-distribution behaves like a standard normal distribution.

5.True False  As the degrees of freedom increase, the shape of the t distribution gets farther away from the shape of the standard normal distribution.

6.True False  The dependence assumption for an independent groups t-test requires that each data point be related to every other data point in the study.
