  1. 4. for proportion problems, population times proportion must be more than or equal to 10 (as well as n(1-p)) and for mean problems, population must be at least 30
  2. 6. standard deviation of a statistic is estimated from data
  3. 7. probability that the value of a parameter falls within a specified range of values
  4. 11. is this if states that a parameter is larger than the null hypothesis or if it states that the parameter is smaller than the null value
  5. 14. a range of values so defined that there is a specified probability that the value of a parameter lies within it
  6. 15. had to estimate the population standard deviation
  7. 17. the value of the statistic from a sample that provides an estimate of the population
  8. 18. reject the null when it is true (false negative)
  9. 19. how close the estimate tends to be to the unknown parameter in repeated random sampling

  1. 1. 10 times the proportion size must be equal to or less than the problem's population
  2. 2. claim tested by a statistical test
  3. 3. claim about the population that we are trying to find evidence for
  4. 5. is this if it states that the parameter is different from the null hypothesis value (could be larger or smaller)
  5. 8. the probability that the statistic (computed assuming the null hypothesis is true)would take a value as extreme as or more extreme than the one actually observed
  6. 9. assesses the evidence provided by data against the null hypothesis in favor of an alternative perspective
  7. 10. fail to reject the null when it is false (false positive)
  8. 12. is this if the p-value is smaller than alpha
  9. 13. must check random, normal, and independent
