What is the alternate hypothesis in a problem where sales group two is predicted to be “…significantly less productive than sales group one?” Question 4. Using the T-test: Two-sample Assuming Equal Variances test, the output can provide… Question 5. To find the normal curve probability of exceeding a specific z-score, which Excel function could be used? Question 6. When interpreting the effect size, a high effect is shown by a value equal to or greater than”. Question 7. Using the Data Analysis Descriptive Statistics tool, the output can provide the … Question 8. Using alpha = .05, what is your decision if the p-value is 0.01 for a one-tail test? Question 9. Which of the following defines statistical significance Question 10. If the p-value is greater than (>) our decision criteria, alpha, then we reject the null hypothesis claim of no difference. BUS 308 Week 2 Quiz Set 2 Question 1. Which statement is not true? Question 2. If the p-value is less than (<) our decision criteria, alpha, then we reject the null hypothesis claim of no difference. Question 3. Using alpha = .05, what is your decision if the p-value is 0.01 for a one-tail test? Question 4. To use Excel to compare a single sample mean against a specific value, a Two Sample with unequal variance t-test can be used if the second “sample” has the same count and consists of only the specific Ho value (resulting in no variation). This gives us a test outcome that is the same as a one sample t-test result. Question 5. What is the alternate hypothesis in a problem where sales group two is predicted to be “…significantly less productive than sales group one?” Question 6. To find the normal curve probability of exceeding a specific z-score, which Excel function could be used? Question 7. Which statement is correctly stated? Question 8. Using alpha = .05, what is your decision if the p-value is 0.01 for a two-tail test? Question 9. To find the z-score of a value, which Excel function could be used? Question 10. Using alpha = .05, what is your decision if the p-value is 0.04 for a two-tail test? BUS 308 Week 2 Quiz Set 3 Question 1. To use Excel to compare a single sample mean against a specific value, a Two Sample with unequal variance t-test can be used if the second “sample” has the same count and consists of only the specific Ho value (resulting in no variation). This gives us a test outcome that is the same as a one sample t-test result. Question 2. The sign of =/= means “not equal”. Question 3. We can use the F-test for variance” to decide if we should use the equal or unequal variance version of the Two Sample T-test. Question 4. The arrow head in the null hypothesis shows which tail the result needs to be in to reject the null. Question 5. If the p-value is less than (<) our decision criteria, alpha, then we reject the null hypothesis claim of no difference. Question 6. Using the Data Analysis Descriptive Statistics tool, the output can provide the … Question 7. Which of the following defines statistical significance Question 8. In a one-tail test, which of the following statements is true? Question 9. When interpreting the effect size, a high effect is shown by a value equal to or greater than”. Question 10. To find the z-score of a value, which Excel function could be used?
