In N = 25 games last season, the college basketball team averaged µ = 76 points with a standard deviation of s = 6.  In their final game of the season, the team scored 89 points.  Compared to the last season average points, the number of points scored in the final game was ____.

For a perfectly symmetrical distribution with µ = 30, what is the most probable value for the mode?

In a related-samples t-test, what concept does the numerator of the t-ratio measure?

Assume that any mean difference is significant. Describe the effects for the table below:   B1 B2 A1 18 16 A2 22 20

A graduate student is conducting a research study to determine if 3 different brands of pre-workout supplements affect the rate of muscle growth. In each treatment, the researcher uses a sample of n = 10 people in each treatment. What is N?

A researcher reports t(12) = 2.86, p < .05 for a repeated-measures research study.  How many individuals participated in the study?

A population has a mean of µ = 30.  If 3 points are added to each score, what is the mean for the new distribution?

The sum of the squared deviation scores is SS = 20 for a sample of n = 5 scores.  What is the variance for this sample?

An analysis of variances produces dfbetween = 3 and dfwithin = 24.  If each treatment has the same number of participants, then how many participants are in each treatment?

A research report concludes that there are significant differences among treatments, with “F(2, 27) = 8.62, p < .01.”  If the same number of participants was used in all of the treatment conditions, then how many individuals were in each treatment?
