Find the value of z that would be used to test the difference between the proportions, given the following. (Use G - H. Give your answer correct to two decimal places.)

Question

Sample n x
G 375 324
H 414 333

Answer 1

Sample n x
G 375 324
H 414 333

n1 = 375
x1 = 324
p1 = x1/n1 = 324/375 = .864
n2 = 414
x2 = 333
p2 = x2/n2= 333/414 = .804

z = 2.24
p-value = .025

Answer 2

Thanks!!
