So we multiply 2 by 12, and get 24.
Then we multiply 8 by 3, and get 24.
Next we give both terms new denominators -- 3 × 12 = 36.
So now our fractions look like this:
<span><span>24/36</span>−<span>24/36</span></span><span><span>Since our denominators match, we can subtract the numerators.24 − 24 = 0So the answer is:<span>0/36 z</span></span><span>ero divided by anything is just zero. So that's the final answer:

Answer:
The estimate of a population proportion is approximately 541.
Step-by-step explanation:
We can solve the the problem by using the formula for minimum sample needed for interval estimate of a population proportion which is given by the formula
n = pq ((Z/2) / E)^2
As, p is not defined so we use the standard p and q which is 0.5 and 0.5.
The reason for this is we have to choose form 0.1 to 0.9 both values of p and q, we will find the maximum value of pq occurs when they both are 0.5.
Next, we will find the value of (Z/2) by looking at the Z-table, we will find that at 98% confidence (Z/2) = 2.326. Now we start substituting the values in the above formula
n = (0.5)×(0.5) × (2.326/0.05)^2
n = 541.027
n ≅ 541.
