  2. 7. If we reject H0 when H0 is true, we have committed a....
  3. 9. The value of that statistic from a sample
  4. 10. a parameter is larger than the null hypothesis value or if it states that the parameter is smaller than the null value
  5. 11. The mean of the sampling distribution of X is the same as the unknown mean μ of the entire population.
  6. 12. 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.
  7. 13. If the P-value is smaller than alpha, we say that the data is.....
  8. 15. Formal procedure for comparing observed data with a claim
  9. 16. one minus the sample size.
  10. 18. a statistic that provides an estimate of a population parameter.
  11. 19. claim tested by a statistical test
  12. 20. tells how close the estimate tends to be to the unknown parameter in repeated random sampling.

  1. 1. 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
  2. 2. Because the population distribution is Normal, so is the sampling distribution of X. Thus, the Normal condition is met.
  3. 3. claim about the population that we are trying to find evidence
  4. 4. which gives the overall success rate of the method for calculating the confidence interval.
  5. 5. The standard deviation of X for an SRS
  6. 8. of a statistic is estimated from data
  7. 14. For a parameter two parts An interval calculated from the data, which has the form estimate plus or minus margin of error
  8. 17. parameter is different from the null hypothesis value (it could be either larger or smaller).
