Using a two-tailed one-sample z-test from a sample of size n, a researcher rejects the null hypothesis as z = 2.0 is greater than the critical value 1.96 at α = .05. What does this mean? Choose ALL the correct options from the following. a. As α = .05, the probability that the null hypothesis is correct is less than 5% b. As α = .05, the probability that the alternative / research hypothesis is correct is more than 95%...
QUESTION 11 You run an independent samples t-test between two groups, and find a t-statistic of t=1.67. Is this sufficient to reject the null hypothesis? Assume α=0.05 and a one-sided test. Yes, > 1.67 is sufficient to reject the null. No, > 1.67 is not sufficient to reject the null. Not enough information. 2 points QUESTION 12 In a dependent samples t-test, the sample sizes must be equal. True False 2 points QUESTION 13 In an independent samples...
A researcher calculates is doing a two-tailed test and calculates a test statistic of z=-1.69 and her level of significance (alpha) is 0.05. Does she reject the null hypothesis? a) Yes b) No c) Need more information
two samples of n=5 subjects were analyzed with an independent -samples t-test, producing a t=2.295 does this indicate a significant difference in a two tailed test with alpha= .05?
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
