Increasing the sample size results in ____ in the standard error of the difference.

All t values that fall within the critical values constitute a(n) _____ result or more formally, the _____ region.

For the previous problem about bone size, what is the correct conclusion? [Fail] the null hypothesis, the number of days it took the small bone group to progress [did_not_differ_from] the number of days it took the large bone group to progress.

When asked to explain the “nature of the relationship” you should describe                                       .

If a mean difference is 6, the estimated standard error of a mean difference is .50 and the nondirectional critical value of t for an alpha level of .05 is 2, what is the 95% confidence interval for the mean difference

The mean of a sampling distribution of the difference between two independent means is always equal to the:

The degrees of freedom for the independent groups t test are equal to:

The standard deviation of the sampling distribution of the difference between two independent means is called the:

The homogeneity of variance assumption states

If a mean difference is 5, the estimated standard error of a mean difference is 4 and the nondirectional critical value of t for an alpha level of .05 is 2, what is the 95% confidence interval for the mean difference
