Determine whether the normal distribution can be used to compare the following population proportions. n1 = 35, n2 = 27. P1 = 0.829, P2 = 0.926 Step 1 of 2: Calculate the four values nip, . n (1 - P, ). n2p2. and n2 (1 - P2). Round your answers to three decimal places, if necessary. Answer 2 Points Tables Keypad Keyboard Shortcuts nip = n (1 - PI) = Prev Next n2p2 = n2 ( 1 - P2) =Determine whetherthe normal distribution can be used to compare the following populaoon proportions. n1 : 35, n2 : 27. 3;. : 0.829, z : 0.92:. step 2 012: Are the conditions for using the normal distribution met? Answer 1 Point 0 Not enough information to determine 0 The conditions are met so the normal distribution can he used. 0 The conditions are not met so the normal distribution can be used. 0 The conditions are not met so the normal distribution cannot be used.
