Across
  1. 3. how close the estimate tends to be to the unknown parameter
  2. 4. the claim about the population we are trying to find evidence for
  3. 8. gives the overall success rate of the confidence interval
  4. 10. a claim tested by a statistical test
  5. 15. gives an interval of plausible values for a parameter
  6. 18. error if we fail to reject Ho when Ho is false
  7. 19. describes a value of a parameter if it is reasonable based on data
Down
  1. 1. of the sample mean where sx is the sample standard deviation
  2. 2. if the p value is smaller than alpha
  3. 5. what you are checking for when you make sure the population is 10x the sample size
  4. 6. the probability that the statistic would take a value as extreme or more extreme than the one actually observed
  5. 7. use for t distribution with n-1
  6. 9. a formal procedure for comparing observed data with a claim
  7. 11. statistic that provides an estimate of a population parameter
  8. 12. if a parameter is different from the null value (either larger or smaller)
  9. 13. if a parameter is larger or smaller than the null value
  10. 14. the standard deviation of a statistic estimated from the data
  11. 16. error if we reject Ho when Ho is true
  12. 17. the probability calculations remain accurate when a condition is violated
  13. 19. the probability that the test will reject Ho at a chosen significance level when the specified alternative value of the parameter is true
