Across
- 6. this test is approximately correct when the data is random, normal, and independent
- 7. a range of values so defined that there is a specified probability that the value of a parameter lies within it
- 8. if the p-value is smaller than alpha, we say that the data is
- 10. the alternative hypothesis is ________ if it states that the parameter is different from the null hypothesis value (it could be either larger or smaller)
- 12. the probability that the test will reject Ho at a chosen significance level when the specified alternative value of the parameter is true
- 13. measures how far a sample statistic diverges from what we would expect if the null hypothesis were true
- 14. both population distributions are normal OR both sample/group sizes are large
Down
- 1. the claim tested by a statistical test
- 2. assesses the evidence provided by the data against a null hypothesis in favor of an alternative hypothesis
- 3. the probability that the statistic would take a value as extreme as or more extreme than the one actually observed is called the
- 4. the claim about the population that we are trying to find evidence for
- 5. random, normal, and independent
- 9. if we reject Ho when Ho is true, we have committed a
- 11. the alternative hypothesis is ________ if it states that a parameter is larger than the null hypothesis value or if it states that the parameter is smaller than the null value
- 13. if we fail to reject Ho when Ho is false, we have committed a
