Post by: tyrich on Mar 19, 2018 A researcher conducts a hypothesis test to evaluate the effect of a treatment. The hypothesis test produces a z-score of z = 2.37. Assuming that the researcher is using a two-tailed test, what decision should be made?
A) The researcher should reject the null hypothesis with = .05 but not with = .01. B) The researcher should reject the null hypothesis with either = .05 or = .01. C) The researcher should fail to reject H0 with either = .05 or = .01. D) The researcher should ignore the results. Question 2 One use of a regression equation is to increase the accuracy of predicting Y scores. What determines the proportion of the variability in the Y scores that is predicted by the regression equation? A) r2 B) 1 - r2 C) r D) 1 - r Question 3 The critical boundaries for a hypothesis test are z = +1.96 and 1.96. If the z-score for the sample data is z = 1.90, then what is the correct statistical decision? A) Fail to reject H1 B) Fail to reject H0 C) Reject H1 D) Reject H0 Title: A researcher conducts a hypothesis test to evaluate the effect of a treatment. The hypothesis test ...
