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