What is the critical value for a repeated measures ANOVA with N=77, 6 levels for factor A, dfWG = 121, and an alpha level of 0.05?

An independent-measures research study uses two samples, each with n = 12 participants.  If the data produce a t statistic of t = 2.08, then which of the following is the correct decision for a two-tailed hypothesis test?

A set of n = 10 pairs of scores has ΣX = 20, ΣY = 30, and ΣXY = 74.  What is the value of SP for these data?

A sample of 30 people is selected from a population with an unknown mean. The one-sample t estimation equation is used to compute the 99% confidence interval around µ. Which of the values below should be used for t in this equation?  µ = 40 ± ( t )( 4 )

A researcher uses a repeated-measures ANOVA to test for mean differences among three treatment conditions using a sample of 10 participants.  What are the df values for the F-ratio from this analysis?

You have a score of X = 65 on an exam.  Which set of parameters would give you the best grade on the exam?

A set of n = 35 pairs of scores (X and Yvalues) produces a regression equation of Ŷ = 12X + 14. Find the predicted Y value for an X score of 2.

A population of scores has µ = 50 and s = 5.  If every score in the population is multiplied by 3, then what are the new values for the mean and standard deviation?

A sample of 30 people is selected from a population with an unknown mean. The one-sample t estimation equation is used to compute the 99% confidence interval around µ. Which of the values below should be used for t in this equation?  µ = 40 ± ( t )( 4 )
