Step-by-step explanation:
The formula for a - level confidence interval for the population proportion:-
Given : n = 225 ; p = 0.60 ;
By using the given information , the confidence interval for the population proportion:-
Hence, the resulting confidence interval is .
< A = 40
< B is a complement of < A....so < B = (90 - 40) = 50
< C is a supplement of < B....so < C = (180 - 50) = 130
Answer:
for brand A it required 41 bags and for brand B is required 56 bags
Step-by-step explanation:
The computation is shown below:
Let us assume Brand A be x
And, brand B be y
Now according to the question
The following equations are
8x + 7y = 720
4x + 6y = 500
Multiply by 2 in equation 2
8x + 7y = 720........(1)
8x + 12y = 1000..........(2)
Now subtract equation 1 from equation 2
5y = 280
y = 56 bags
And, x is
8x + 7(56) = 720
8x + 392 = 720
8x = 328
x = 41 bags
hence, for brand A it required 41 bags and for brand B is required 56 bags
