Divide the total by 2 and you'll get A and B = 31,364
Answer:
We need 232 mL of Compound A
Step-by-step explanation:
We know the ratio
A : B : total
4 3 4+3
4 3 7
We want 406
406 /7 =58
Multiply each part by 58
A : B : total
4*58 3*58 7*58
232 174 406
We need 232 mL of Compound A

Answer:
<em> 85% level of the confidence interval is</em>
<em>(26.337, 26.662)</em>
Step-by-step explanation:
<u><em>Explanation</em></u>:-
Given the size of the sample 'n' = 295
Mean of the sample x⁻ = 26.5
The Standard deviation of the Population = 2.7
85% level of the confidence interval is determined by

Critical value Z₀.₁₅ = 1.036
<em> 85% level of the confidence interval is determined by</em>


( 26.5 - 0.1628 , 26.5+0.1628)
(26.3372,26.6628)
