If you have a one-tailed test and the critical value is 1.65,
when would you reject the null hypothesis?
A. Test statistic is -1.5
B. Test statistic is -2
C. Test statistic is 0
D. Test statistic is 2
If you have a one-tailed test and the critical value is 1.65, when would you reject...
If the cutoff for a one-tailed z test is -1.65, choose which of the following z scores would cause you to reject the null hypothesis: a)-1.2 b)-3.5 c)-2.3 d)2.5 e)-1.96 f)1.5 g) 0
You are performing a two-tailed test. If α = .004 , find the positive critical value, to three decimal places. zα/2 = You are performing a left-tailed z-test If α=.025, and your test statistic is z=−1.75, do you: Reject Null Hypothesis Fail to Reject Null Hypothesis
In a one-tailed t-test, the null hypothesis is H0: population β1≥0. If the test statistic = – 1.529, and the critical value you find from the t-table is 2.164, do you reject the null hypothesis?
I spefically need to see how
the test statistic and critical value is calculated.
Test the claim that the proportion of men who own cats is significantly different than 80% at the 0.02 significance level. The null and alternative hypothesis would be: The test is: left-tailed right-tailed two-tailed Based on a sample of 55 people, 78% owned cats The test statistic is: (to 2 decimals) The positive critical value is: (to 2 decimals) Based on this we: Reject the null...
For a one-tailed hypothesis test where you reject Ho only in the lower tail, the critical value is-1.7247. What is the statistical decision if teTAT -2.69? What is the statistical decision? OA Since the teraT Value is greater than or equal to the critical value, reject Hn. OB. Since the tgTAT value is less than the critical value, reject Ho- O C. Since the teTAT value is greater than or equal to the critical value, do not reject Hg- OD....
you are completing a hypothesis test. You know the following items: The test is a right-tailed test. The critical value for the test is 8.547 The standardized test statistic is 8.394. Decide whether to reject or fail to reject the null hypothesis.
You are completing a hypothesis test. You know the following items: The test is a two-tailed test. The critical value for the test is + 2.763 The standardized test statistic is -2.768 Assume the population is normally distributed. Decide whether to reject or fail to reject the null hypothesis.
All things being equal, when we have a two-tailed Alternative Hypothesis test it is easier to reject the Null Hypothesis (when compared to a one-tailed test). True False
(a) For the same data and null hypothesis, is the P-value of a one-tailed test (right or left) larger or smaller than that of a two-tailed test? pick one The P-value for a one-tailed test is smaller because the two-tailed test includes the area in both tails. The P-value for a one-tailed test is larger because the two-tailed test includes the area in only one tail. The P-value for a one-tailed test is larger because the two-tailed test includes the...
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...
