When a researcher wants to perform the test of significance of differences between two percentages,each representing a separate group(sample),what is the SECOND required step?
A)The difference is translated into a number of standard errors away from the hypothesized value of zero.
B)The difference is translated into a number of standard errors closest to the hypothesized value of zero.
C)The percentage is translated into a number of standard errors away from the hypothesized value of zero.
D)The difference is translated into a number of standard errors away at the hypothesized value of zero.

The second required step is to calculate the standard error of the difference, which is obtained by using the formula of standard error of difference between two percentages. The difference between two percentages is then translated into a number of standard errors away from the hypothesized value of zero (which is usually zero in the absence of any significant difference between the two groups). This allows the researcher to determine whether the observed difference is statistically significant or not, using the appropriate statistical test (e.g., z-test or t-test).
