Question

1) Which of the following statements about Type I and Type II errors is correct: A Type I:   Reject a true alternative hypothesis.   Type II: Do not reject a false alternative. B Type I:   Reject a true null hypothesis.   Type II: Do not reject a false null hypothesis. C Type I:   Do not reject a false null hypothesis.   Type II: Reject a true null hypothesis. D Type I:   Reject a false null hypothesis.   Type II: Reject a true null hypothesis. 2) In a test of hypothesis, the symbol ? represents: A The level of significance, or the probability of rejecting a true H?. B The level of significance, or the probability of not rejecting a false H?. C The power of the test, or the probability of rejecting a false H?. D The level of significance, or the probability of committing a Type II error. 3) Suppose in a test of hypothesis the probability value (p-value) is 0.0694. Then you should, A not reject H? at ? = 0.10. B reject H? at ? = 0.05. C reject H? at ? = 0.10, but not reject H? at ? = 0.05. D reject H? at ? = 0.05, but not reject H? at ? = 0.10. 1) Which of the following statements about Type I and Type II errors is correct: A Type I:   Reject a true alternative hypothesis.   Type II: Do not reject a false alternative.
