Answer: 0.8
. . . . . . . . . . .
Answer:
It would change to 0.04802
Step-by-step explanation:
from this question we have that n became 400
40% of 400
= 160
p* = 160/400
= 0.4
1 - p* =
= 1 - 0.4
= 0.6
at confidence level,
1 - 0.95
= 0.05
alpha/2 = 0.025
z= 1.96
<u>margin of error. E</u>
= 1.96 x √[(0.4 x 0.6)/400]
= 1.96 x 0.0245
= 0.04802
M.E = 0.04802
1 over 3 should be the answer I think
No they wont have the same amount because adele will have 50 dollars more each month
3:1 , 4*3=12, 5*1=5
Ratio is 3:1
