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