Calculate the standard error. May normality be assumed? (Round your answers to 4 decimal places.) Standard Error

(a) n = 30, π = .60

(b) n = 58, π = .57

(c) n = 110, π = .59

(d) n = 550, π = .006

Homework Answers

Answer #1

Standard error. SE =

a) n = 30,   = 0.60

Standard error =

= 0.0894

b) n = 58,   = 0.57

Standard error =

= 0.0650

a) n = 110,   = 0.59

Standard error =

= 0.0469

a) n = 550,   = 0.006

Standard error =

= 0.0033
