If the coefficient of determination is .09 and the sum of squares regression is 88, then the total variation in Y must be SSY = 108.

The value of power is influenced by the alpha level, sample size, and effect size.

The coefficient of determination is mathematically equivalent to h2.

A researcher randomly assigns 24 participants to one of four groups. At a .05 level of significance, the critical value for a one-way between-subjects ANOVA is 3.49.

A researcher measures the relationship between narcissism and willingness to help. If SSXY = 240, SSX = 320, and SSY = 410, then what is the value of the correlation coefficient?

A professor finds that the average SAT score among all students attending his college is 1,150 ± 150 (m ± s). He polls his class of 25 students and finds that the average SAT score is 1,200. Suppose he computes a one-sample z test at a .05 level of significance. What is his decision?

A researcher wants to know the probability of selecting a student athlete from a school population where 5% of students are athletes. If the researcher selects a sample of 120 students, is it appropriate to use the normal approximation of the binomial distribution to estimate this probability?

The greater the power, the more likely we are to correctly reject the null hypothesis, if it is incorrect.

A researcher measures mating displays among 12 birds randomly assigned to be in the presence of no cue, an auditory cue, or a visual cue. The degrees of freedom for this one-way between-subjects ANOVA are 2 and 9.

A researcher selects a sample of nine participants from a population with a mean of 8 and a standard deviation of 3. About 14% of the sample means in this sampling distribution should be between a sample mean of ______.
