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 the null hypothesis (H0)?
A) For A reject; For B reject
B) For A fail to reject; For B reject
C) For A fail to reject; For B fail to reject
D) For A reject; For B fail to reject
2) For a right tailed test, if we have a t critical of 1.658 and a t obtained of 1.73, what decision do we make regarding the null hypothesis (H0)?
For a left tailed test, if we have a t critical of -1.658 and a t obtained of -1.42, what decision do we make regarding the null hypothesis (H0)?
A) fail to reject; reject
B) reject; fail to reject
C) reject; reject
D) fail to reject; fail to reject

Find the critical value for the indicated hypothesis test, then use this value and the provided information to make a conclusion about the null hypothesis (i.e., reject or fail to reject the null hypothesis). 1.The test statistic in a left-tailed test is z = −2.05; significance level α = 8% 2. Test at the significance level α = 5% the hypothesis H0: p ≤ 0.04, given that the test statistic is z = 1.82. 3. Test at the significance level...

A sample of size 100, taken from a population whose standard deviation is known to be 8.90, has a sample mean of 51.16. Suppose that we have adopted the null hypothesis that the actual population mean is greater than or equal to 52, that is, H0 is that μ ≥ 52 and we want to test the alternative hypothesis, H1, that μ < 52, with level of significance α = 0.05. a) What type of test would be appropriate in...
