In a one-sample t-test if the critical value is 4.25 and the obtained value is 4.3, what decision should be made about the null hypothesis?

A set of 10 scores has SS = 90.  If the scores are a sample, the sample variance is ____ and if the scores are a population, the population variance is ____.

Which of the following statements cannot be true for a distribution of scores?

Using an independent-measures t, the 90% confidence interval for the difference between two population means ranges from 19 to 23.  Based on this confidence interval, you can conclude that the difference between the two sample means is ____.

What type of variable(s) is used for a Bivariate Correlation?

In analysis of variance, what is measured by the MS values?

In general, if the variance of the difference scores increases, then what will happen to the value of the t statistic? Hint: variance of the difference score is in the denominator.

In a sample with M = 40 and s = 8, what is the z-score corresponding to X = 38?

A set of 10 scores has SS = 90.  If the scores are a sample, the sample variance is ____ and if the scores are a population, the population variance is ____.

Using an independent-measures t, the 90% confidence interval for the difference between two population means ranges from 19 to 23.  Based on this confidence interval, you can conclude that the difference between the two sample means is ____.
