  1. 4. claim about the population that we are trying to find evidence for
  2. 6. alternative states that the parameter is different from the null hypothesis value
  3. 9. probability that the statistic would take a value as entree as or more extreme than the one actually observed, in the direction specified by Ha
  4. 12. when the population distribution isn’t Normal, this statistic will have approximately a tn − 1 distribution if the sample size is large enough
  5. 13. we fail to reject the null hypothesis when the alternative hypothesis is true
  6. 14. if the p-value is smaller than the alpha
  7. 17. probability that the test will reject the null hypothesis at a chosen significance level alpha when the specified alternative value if the parameter is true
  8. 18. value of that statistic from a sample
  9. 19. gives the overall success rate of the method for calculating the confidence interval
  10. 20. data were produced by a well-designed random sample or randomized experiment
Down
  1. 1. if we reject the null hypothesis when it is true
  2. 2. where z* is the standard Normal
  3. 3. claim we weigh evidence against in a statistical test
  4. 5. measures how far a sample statistic diverges from what we expect if the null hypothesis were true
  5. 7. a statistic that provides an estimate of a population parameter
  6. 8. 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. 10. difference between the point estimate and the true parameter value will be less than this
  8. 11. an interval of plausible values for a parameter
  9. 15. has a different shape than the standard Normal curve: still symmetric with a single peak at 0, but with much more area in the tails
  10. 16. when the standard deviation of a statistic is estimated from data
