Answer:The 2nd one
Step-by-step explanation:
Answer:
The answer would be: V1/T1=V2/T2
We need to use the formula to find Margin of Error but through the sample proportion, that is

We will use a 95% confidence interval, that is a z value of 1.96 (Search in a Normal distribution table)
A) For A our
(proportion) is equal to 0.45. So applying the formula,


B) We make the same of point A, but change our proportion to 0.35


c) We need to calculate the SE through proportion for 0.1, that is

Then our Error is given by,



Here we need to calculate common denominator so, LCM of 16 & 24
It would be 48
So, final answer is 48
