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:
C
Step-by-step explanation:
I checked with my older sibling and their a math genius so its correct
Answer:
1980
We can choose 2 men from 9 in 36 in ways.
We can choose 2 women from 11 in 55 ways.
For any arrangement of 2 men there are 55 ways of combining them with 2 women => 55 * 36 = 1980 total ways.
If you're wondering how i got the numbers i used the combination formula:
C(n, k) = 
The answer would be B, because you would just multiply 116.22 by 500
