Across
  1. 6. the confidence interval is sometimes referred to this
  2. 8. a formal procedure for using observed data to decide between two competing claims
  3. 11. of we reject Ho when Ho is true
  4. 12. if we fail to reject Ho when Ha is true
  5. 14. if the p-value is smaller than alpha
  6. 16. probability of getting a sample result at least as extreme as the one we did if the null hypothesis were true
  7. 17. the claim we weigh evidence against in a statistical test
  8. 19. A statistic that provides an estimate of a popular parameter
  9. 20. the alternative hypothesis is this if it states that a parameter is larger than the null hypothesis value or if it states that the parameter smaller than the null value
Down
  1. 1. The value of the point estimator from a sample
  2. 2. if the alternative hypothesis states the parameter is different from the null hypothesis value (could be either larger or smaller)
  3. 3. when conditions are met, a C% confidence interval for the mean is given by this
  4. 4. the difference between the point estimate and the true parameter will be less than this C% of all samples
  5. 5. error this error results when the standard deviation of a statistic is estimated from data
  6. 7. where Sx is the sample standard deviation. It describes how far X will typically be from M in repeated SRSs of size n
  7. 9. gives the overall success rate of the method for calculating the confidence interval
  8. 10. Gives an interval of plausible values for a parameter
  9. 13. the claim about the population that we are trying to find evidence for
  10. 15. the distribution for every positive degrees of freedom
  11. 18. if the p-value is greater than or equal to a and say that we do not have convincing evidence for Ha
