To test Ho: P-0.30 that a population proportion equals 0.30, the test statistic

Question

To test Ho: P-0.30 that a population proportion equals 0.30, the test statistic is a z-score that measures the number of standard errors between the sample proportion and the Ho value of 0.30. If z-0.7, do the data support the nul hypothesis, or do they give strong evidence against it? O A. The data support the null hypothesis because the sample proportion falls over 0.05 standard errors from the null hypothesis value O B. The data give strong evidence against the null hypothesis because the sample proportion falls within three standard errors from the null hypothesis value. C. D The data support the null hypothesis because the sample proportion falls within three standard errors from the null hypothesis value The data give strong evidence against the null hypothesis because the sample proportion falls over 0.05 standard errors from the null hypothesis value

Explanation / Answer

For z = 0.7, we would not be rejecting the null hypothesis so we can instantly eliminate Option B and Option D. In Option A, it talks about 0.05 standard error which we do not know in this case.

Hence,

Option C is correct.
