Question 1. 1. Chi-square tests are parametric in nature – requiring data that fit a specific distribution/shape. (Points : 1)

Question 3. 3. The percent confidence interval is the range having the percent probability of containing the actual population parameter. (Points : 1)
True
False
Question 4. 4. The distribution for the goodness of fit test equals k-1, where k equals the number of categories. (Points : 1)
True
False
Question 5. 5. If the confidence interval for mean differences contains a 0, the associated t-test would have shown a significant difference. (Points : 1)
True
False
Question 6. 6. For a one sample confidence interval, if the interval contains the μm , the corresponding t-test will have a statistically significant result – rejecting the null hypothesis. (Points : 1)
True
False
Question 7. 7. Statistical significance in the Chi-square test means the population distribution (expected) is not the source of the sample (observed) data. (Points : 1)
True
False
Question 8. 8. A confidence interval is generally created when statistical tests fail to reject the null hypothesis – that is, when results are not statistically significant. (Points : 1)
True
False
Question 9. 9. For a one sample confidence interval, the interval is calculated around the calculated sample mean (m). (Points : 1)
True
False
Question 10. 10. Chi-square tests rarely have type I errors. (Points : 1)
True
False
