Explanation / Answer

Part-a

Greater and Option-D

Part-b

Critical value Z=1.28 and Rejection Region: Option-B Z>1.28

Part-c

Test statistic Z=-6.51 (here we converted %ages in to numbers)

Sample    X     N Sample p

1       364 2000 0.182000

2       536 2000 0.268000

Difference = p (1) - p (2)

Estimate for difference: -0.086

95% lower bound for difference: -0.107605

Test for difference = 0 (vs > 0): Z = -6.51 P-Value = 1.000

Part-d

Fail to reject H0

Part-e

Option-D
