Question 8 3 pts The standard error changes as we move from a two-tailed hypothesis test...
The standard error changes as we move from a two-tailed hypothesis test to a one-tailed test. O True O False
Question 4 3 pts The Critical Value changes as we move from a two-tailed hypothes is test to a one-tailed test True False Question 5 3 pts In reference to a Confidence Interval, which are true All the answers are correct The larger the level of alpha, the smaller the Bound of Error (BOE) The larger the level of alpha, the larger the Confidence Coefficient The larger the level of alpha, the larger the standard deviation Question 8 3 pts...
The Critical Value changes as we move from a two-tailed hypothesis test to a one-tailed test. Group of answer choices True False
Question 8 3 pts The a two-tailed hypothesis test Is related to a confidence interval at the same level of alpha. All of the answers are true. Is expressed in a probability framework with a chance of being wrong in our conclusion. Has an alternative hypothesis that uses Not Equal in the expression For this problem you will need a t-table. What is the t-value needed for the critical value for a one-tailed upper hypothesis test with a sample size...
Question 4 1 pts Classify the hypothesis test as left-tailed, right-tailed, or two-tailed. In 1990, the average duration of long-distance telephone calls originating in one town was 7.2 minutes. A long-distance telephone company wants to perform a hypothesis test to determine whether the average duration of long-distance phone calls has changed from the 1990 mean of 7.2 minutes Right-tailed Two-tailed O Left-tailed
Question 6 2 pts For a two-tailed hypothesis test with a = .05 and a sample of n = 25 scores, the boundaries for the critical region are t = +2.060. O False o True
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
Compared to a two-tailed hypothesis test, a one-tailed test is more likely to detect a: Group of answer choices true null hypothesis in the direction of concern false null hypothesis in the direction of concern false null hypothesis true null hypothesis
Question 2 3 pts The standard error is the same things as the standard deviation True Question 19 3 pts False Small Sample Mean Problem. Each year the Heritage Foundation creates an Index of Economic Freedom for countries around the word based on assessments of freedom on property rights.corruption business freedom, and labor freedom, among many others. We have a sample of 31 countries taken from the 2016 data. The following is a summary of this sample. Question 32 3...

O We fail to reject the null hypothesis at the alpha level 0.1 We reject the null hypothesis at the alpha level of 0.05 We reject the null hypothesis at the alpha level of 0.01 O We fail to reject the null hypothesis at the alpha level 0.05 Question 15 4 pts
