Suppose you are testing H0: p = .63 versus Ha: p = .63 .For a random sample of 100 people, where x denotes the number in the sample that have the characteristic of interest. Use a .01 level of significance to test this hypothesis.
Answer to relevant QuestionsSuppose you are testing H0: p = .29 versus Ha: p ≠ .29 A random sample of 740 items shows that 207 have this characteristic.
