Answer:
Step-by-step explanation:
The error in rounding a number is half of the unit of measure.
The number was rounded to the nearest 0.1 unit so the error is 1/2×0.1, which equals 0.05.
Now we add 3.7 and 0.05, which equals 3.75 and we also take 3.7 - 0.05, which equals 3.65
So, the error interval is:
When 0 is in the numerator, then the whole fraction becomes equal to 0.
However if 0 is in the denominator, then it is undefined.
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.
