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....
The test statistic in a left-tailed test is z= - 1.33. Determine the P-value and decide whether, at the 10% significance level, the data provide sufficient evidence to reject the null hypothesis in favor of the alternative hypothesis. BE!

1) Select the answer with the correct choices for scenarios A and B regarding the null hypothesis (H0). Scenario A - If we have chosen an alpha (α) of .05 for a two tailed test and our Z obtained is 1.70, what decision do we make regarding the null hypothesis (H0)? Scenario B - If we have chosen an alpha (α) of .01 for a left tailed test and our Z obtained is -2.24, what decision do we make regarding...
