You can do Guess and Check(but the smart way). You first get 102 and 12. Then, you can minus 3 from each one of them, getting 99 and 9, also being 11 times the other, so then the answer would be 180 - 99 or 90 - 9, equaling 81
Answer: Margin of Error for the given CI is 0.08
Step-by-step explanation:
Given the data in the question;
it is a symmetric class interval hence, sample proportion p = (0.50 + 0.66) / 2
p = 1.16 / 2
sample proportion p = 0.58
Margin of Error E will be;
E = 1/2 × length of Confidence interval
Margin of Error E = 1/2 × ( 0.66 - 0.5)
Margin of Error E = 1/2 × 0.16
Margin of Error E = 0.08
Therefore; Margin of Error for the given CI is 0.08

The true statement
The question is incomplete, as no option is given.
I will solve generally, as follows;
A linear equation is represented as:
Where
slope
y intercept
So, by comparison:
Hence, the graph has a slope of -3 (a negative slope)
And the y intercept of 2
