Across
- 5. The sampling distribution of the statistic is approximately Normal
- 6. 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
- 7. The probability, computed assuming H0 is true, that the statistic (such as ôop or X) would take a value as extreme as or more extreme than the one actually observed
- 8. Study designs that involve making two observations on the same individual
- 10. a formal procedure for comparing observed data with a claim (also called a hypothesis) whose truth we want to assess
- 11. sometimes referred to as an interval estimate
- 13. depends on both the confidence level C and the sampling distribution of the statistic
- 15. claim about the population that we are trying to find evidence for
- 17. The data come from a well-designed random sample or randomized experiment
- 18. If we reject H0 when H0 is true
Down
- 1. claim tested by a statistical test
- 2. tells how close the estimate tends to be to the unknown parameter in repeated random sampling
- 3. Individual observations are ___________
- 4. gives the overall success rate of the method for calculating the confidence interval
- 9. If we fail to reject H0 when H0 is false
- 10. If the P-value is smaller than a specified value α (called the significance level), the data are __________________
- 12. a statistic that provides an estimate of a population parameter
- 14. When the standard deviation of a statistic is estimated from data, the result is called the __________ of the statistic.
- 16. the value of that statistic from a sample
- 19. The ______ of a test against a specific alternative is the probability that the test will reject H0 at a chosen significance level α when the specified alternative value of the parameter is true
