How will the outcomes for the two samples compare : Two samples from the same population both have M = 84 and s2 = 20, however one sample has n = 10 and the other has n = 20 scores. Both samples are used to evaluate a hypothesis that ? = 80 and to compute Cohen’s d. How will the outcomes for the tw..

Difference between a hypothesis test : Which of the following is a difference between a hypothesis test with the t statistic and a test with a z-score?

The boundaries of the critical region : What t values form the boundaries of the critical region for a two-tailed test using a sample of n = 9 scores and an alpha level of 0.05?

What is the sample variance : A sample of n = 25 scores has a mean of M = 65 and an estimated standard error of 2 points. What is the sample variance?

Calculate the estimated standard error : A sample of n = 16 individuals is selected from a population with µ = 30. After a treatment is administered to the individuals, the sample mean is found to be M = 33. If the sample variance is s2 = 64, then calculate the estimated standard error a..

Likelihood of rejecting the null hypothesis : As the sample size increases, what happens to the likelihood of rejecting the null hypothesis and what happens to measures of effect size such as r2 and Cohen’s d?

Correct statistical decision for this sample : 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 ? = .05, what is the correct statistical decision for this sample?
