To test H 0: p=0.40 that a population proportion equals 0.40, the test statistic is a z-score that measures the number of sta

ndard errors between the sample proportion and the H0 value of 0.40. If z=3.8, do the data support the null hypothesis, or do they give strong evidence against it?
(A) The data give strong evidence against the null hypothesis because the sample proportion falls over three standard errors from the null hypothesis value.
(B) The data support the null hypothesis because the sample proportion falls over three standard errors from the null hypothesis value.
(C) The data give strong evidence against the null hypothesis because the sample proportion falls within four standard errors from the null hypothesis value.
(D) The data support the null hypothesis because the sample proportion falls within four standard errors from the null hypothesis value.
