At a minimum, set up the entire formula and round your final answer to two decimal places. Recall that, cum fp = (% of scores below the percentile point) x N. Py=X,; +(~;](cum fp cum fz) i which converts to: Py = A+(](D E) Specify the values (from the formula set-up). All numbers should be rounded and/or reported to two decimal places (e.g. 1 =incorrect answer -= 1 00 = correct answer). A= Pgp=
