A researcher obtains t = 2.25 for a repeated-measures study using a sample of n = 10 participants. Based on this t value, what is the correct decision for a two-tailed test? Reject the null hypothesis with a -.05 Reject the null hypothesis with a -01 Fail to reject the null hypothesis with a - .05 Cannot determine without additional information

Based on this report, what was the statistical decision? (a) The null hypothesis was rejected and the probability of a Type I error is less than .05. b. The null hypothesis was not rejected and the probability of a Type I error is less than .05. e. The null...

A researcher uses two samples, each with n = 15 participants, to evaluate the mean difference in performance scores between 8-year-old and 10-year-old children. The prediction is that the older children will have higher scores. The sample mean for the older children is five points higher than the mean for the younger children and the pooled variance for the two samples is 30. For a one- tailed...

Multiple Choice: Question #1 A two tailed hypothesis test is being used to evaluate a treatment effect with ( a = .05). if the sample data produce a Z-score of ( z= -2.24), what is the correct decision? A. Reject the null hypothesis and conclude that the treatment has no effect B. Reject the null hypothesis and conclude that the treatment has an effect C. Fail to reject the null Hypothesis and conclude that the treatment has no effect D....

A research report describing the results from a repeated-measures t test states, "t(22) 1.71, p> .05." From this report you can conclude that the outcome of the hypothesis test was to reject the null hypothesis with a sample of n = 23 participants b.) to fail to reject the null hypothesis with a sample of n = 23 participants to reject the null hypothesis with a sample of n = 22...
