Use Table A to find the value zz of a standard Normal variable that satisfies each of the following conditions. (Use the value of zz from Table A that comes closest to satisfying the condition.) In each case, sketch a standard Normal curve with your value of zz marked on the axis. (a) The point zz with 61 % of the observations falling below it zz (±±0.01; that is round to two decimal places) = (b) The point zz with 21 % of the observations falling above it zz (±±0.01; that is round to two decimal places) =
