Calculate the standard error. May normality be assumed? (Round your answers to 4 decimal places.) Standard Error Normality (a) n = 20, π π = .21 (b) n = 48, π π = .27 (c) n = 117, π π = .53 (d) n = 593, π π = .002

Three numbers x, y, and z are in the ratio 2: 7: 8. if 12 is subtracted from y, then three numbers form a geometric sequence (in the order x, y–12, z). find x, y, and z. there are 2 sets.
