I just need help with the LAST step. I am stuck... Please help!!! The equation for determining the sample size n = can be obtained by solving the equation for the margin of error E = z. Show that this is true and justify each step. ...... A. Rewrite the equation by solving for ze. B. Rewrite the equation by solving for n. O C. Rewrite the equation by solving for E. O D. Rewrite the equation by solving for o. Solve the equation for the specified variable. State the operation to be performed and simplify both sides of the equation. E = Zc Vn Write the original equation.
