Expand the brackets:
2x (3x - 1) + 3
6x - 2x + 3
Collect like terms
6x - 2x + 3
4x + 3
The answer is 4x + 3
so it is 87.5 so what you do do is 25 x 3.50 and it will give you 87.5
Using the confidence interval, it is found that the correct option is:
There is convincing evidence because the entire interval is above 0.
<h3>When does a confidence interval for the difference of proportions gives convincing evidence that there is a difference?</h3>
It gives convincing evidence when 0 is not part of the confidence interval.
In this problem, the interval is (0.02, 0.38), which does not contain 0, hence the correct option is:
There is convincing evidence because the entire interval is above 0.
