What is the critical value for factor A in a Factorial ANOVA with N=77, 6 levels for factor A and 4 levels for factor B, and an alpha level of 0.05?

For the scores shown in the accompanying stem-and-leaf display, what is the highest score in the distribution?

On an exam with µ = 52, you have a score of X = 44.  Which value for the standard deviation would give you the highest position in the class distribution?

On an exam with M = 52, you have a score of X = 56.  Which value for the standard deviation would give you the highest position in the class distribution?

Which of the following sets of data would produce the largest value for an independent-measures t statistic?

A researcher obtains t = 2.35 for a repeated-measures study using a sample of n = 8 participants.  Based on this t value, what is the correct decision for a two-tailed test?

A sample has a mean of M = 39.5 and a standard deviation of s = 4.3, and produces a t statistic of t = 2.14.  For a two-tailed hypothesis test with a = .05, what is the correct statistical decision for this sample?

Under what circumstances can a very small treatment effect be statistically significant?

A sample of n = 5 scores has a mean of M = 12.  What is ΣX for this sample?

In a population of scores, X = 83 corresponds to z = –0.50 and X = 93 corresponds to z = +2.00.  What are the values for the population mean and standard deviation?
