Answer:
D 0.0353
Step-by-step explanation:
a= 0.05. p= 0.65. n=700
S N P = 700 × 065 = 45575
1 n ( 1 - p ) = 700× ( 1 - 0.65 ) = 24575
get the sample is big ,. p~ N ( π. √ π ( 1-π ) p - π
-----------. ------- ~ ( o. 1

the margin of error ∆ = Z a

according to the standard normal distribution,
Z d
---. = zo.o25 = 1.96
2
∆=1.96×√p ( 1 - p ). =. 1.96 × √ 0.65× ( 1 - 65)
---------. ---------

= 0.0353
