Answer:
0.03
Step-by-step explanation:w
standard deviation = ( p(1-p) / n)1/2
p= sample proportion= 55%
n= sample size = 900
standard deviation = ( [55/100] [ 1- 55/100]) / 900)1/2
= (0.55*0.45 / 900)1/2
= 0.0165
margin of error = critical value*standard deviation
[ from graph critical value = 2]
margin of error = 2*0.0165=0.033
Answer: B
Step-by-step explanation:
4.2 / 0.25 = 21
0.4 · 21 = 8.4
8.4 + 2.5 = 10.9
