    Question

    A hypothesis test is conducted for a population proportion. The sample size was 60 and the sample proportion (estimated) was 0.33. For the hypothesis test, calculate the P-value under the null hypothesis which states that the population proportion equals 0.30. The alternative hypothesis is that the population proportion is greater than 0.30. Then the best description of the P value is that it is the probability


    1. TRUE: On the sample proportion or larger given that the population proportion is 0.30.
    2. FALSE: On the population proportion or larger given that the sample proportion is 0.33.
    3. FALSE: On the sample proportion or larger given that the population proportion is greater than 0.30.

    1. On sample proportion or larger given that population proportion is 0.30: Correct
    2. On the population proportion or larger given that the sample proportion is 0.33.: Incorrect
    3. On the sample proportion or larger given that the population proportion is greater than 0.30…: Incorrect
