Across
  1. 5. Probability that the test will reject H0 at a chosen significance level α when the specified alternative value of the parameter is true
  2. 6. Parameter is larger than the null hypothesis value or it is smaller than the null value
  3. 9. statistic ± (critical value) · (standard deviation of statistic)
  4. 10. (1) the population distribution is Normal or the sample size is large (n ≥ 30); and (2) the population is at least 10 times as large as the sample.
  5. 11. If H0 is not rejected when H0 is false
  6. 13. The success rate of the method that produces the confidence interval
  7. 14. Study designs that involve making two observations on the same individual
  8. 16. The specific value of a point estimator.
  9. 18. When the standard deviation of a statistic is estimated from data, the result is this
  10. 20. P-value is less than the chosen significance level α
Down
  1. 1. df = n − 1
  2. 2. Measures how far a sample statistic diverges from what we would expect if the null hypothesis H0 were true
  3. 3. If H0 is rejected when H0 is true
  4. 4. The parameter is different from the null value
  5. 7. Hypothesis The claim tested by a statistical test
  6. 8. Probability, assuming H0 is true, that the statistic would take a value as extreme as or more extreme than the one actually observed
  7. 12. Assesses the evidence provided by data about some claim concerning a population
  8. 15. A statistic that provides an estimate of a population parameter
  9. 17. If the probability calculations involved in that procedure remain fairly accurate when a condition for using the procedure is violated
  10. 19. Tells how close the estimate tends to be to the unknown parameter in repeated random sampling.
