  1. 4. When our P-value is less than the chosen significance level α.
  2. 6. (Sx)(sqrt(n)) where Sx is the sample standard deviation. It describes how far mean x will be from µ , on average, in repeated SRSs of size n.
  3. 8. An interval calculated from sample data, which has the general form estimate ± margin of error or, alternatively, statistic ± (critical value)(standard deviation of statistic). The critical value depends on both the confidence level C and the sampling distribution of the statistic.
  4. 11. The parameter is different from the null value (it could be either smaller or larger).
  5. 13. The specific value of a point estimator.
  6. 15. A parameter is larger than the null hypothesis value or if it states that the parameter is smaller than the null value.
  7. 17. An inference procedure is called robust if the probability calculations involved in that procedure remain fairly accurate when a condition for using the procedure is violated.
  8. 18. Tells how close the estimate tends to be to the unknown parameter in repeated random sampling.
  9. 20. Occurs if H0 is not rejected when H0 is false.
Down
  1. 1. ([p^](1-p^)/n). It describes how far p^ will be from p, on average, in repeated SRSs of size n.
  2. 2. Study designs that involve making two observations on the same individual, or one observation on each of two similar individuals.
  3. 3. Measures how far a sample statistic diverges from what we would expect if the null hypothesis H0 were true, in standardized units.
  4. 5. A statistic that provides an estimate of a population parameter.
  5. 7. The claim about the population that we are trying to find evidence FOR.
  6. 9. The number of values that can vary in a stats calculation
  7. 10. The success rate of the method that produces the confidence interval. In C% of all possible samples, the method would yield an interval that captures the true parameter value.
  8. 12. Occurs if H0 is rejected when H0 is true.
  9. 14. Assesses the evidence provided by data about some claim concerning a population.
  10. 16. When the standard deviation of a statistic is estimated from data, the result is the standard error of the statistic.
  11. 19. The probability that the test will reject H0 at a chosen significance level α when the specified alternative value of the parameter is true.
