1 to say that the null hypothesis is rejected does not, Ask an Expert

Statistics

1. To say that the null hypothesis is rejected does not necessarily mean it is false.

2. In a practical situation, the null hypothesis, alternative hypothesis, and level of rejection should be specified before the experimentation.

3. The probability of choosing a random sample of 3 persons in which the first 2 say "yes" and the last person says "no" from a population in which P(yes) ¼ 0.7 is (0.7)(0.7)(0.3).

4. If the experimental hypothesis is true, chance does not enter into the outcome of the experiment.

5. The alternative hypothesis is often the experimental hypothesis.

6. A decision made on the basis of a statistical procedure will always be correct.

7. The probability of choosing a random sample of 3 persons in which exactly 2 say "yes" from a population with P(yes) ¼ 0.6 is (0.6)(0.6)(0.4).
