TRUE OR FALSE

22. To estimate m within two units with 95% confidence and s = 10 requires n be at least 96.

23. When working with a sample size of n = 9, assuming a one-tailed test, more than 5% of the

area under the appropriate t-curve will be located in the tail beyond 1.65 standard errors.

24. If a two-tailed test assumes a 5% rejection region, then the total rejection region is 10%; that

is, it consists of 5% in each tail.

25. The p-value for a hypothesis test resulting in z > 2.63 is approximately 0.0034.

26. "Statistical significance" may be defined as the rejection of a null hypothesis at some a-level.
