Answer:
We know that x = 10. But, we don't know what f is. In order to find f, we would divide. To divide we would use this formula: 8 ÷ 10. This equals 0.8 or 8 tenths. Now, we know what our <em>f</em> value is. It's 0.8! To double check, use a calculator and type in: 10*0.8 and see if the answer is 8. (Please mark brainliest! :D)
Considering the situation described, the confidence interval is given by:
(0.35, 0.51).
<h3>What is a confidence interval?</h3>
It is given by the <u>estimate plus/minus the margin of error</u>.
For this problem, we have that:
- The margin of error is half the range of the observations, hence M = (0.48 - 0.32)/2 = 0.08.
Then, the bounds of the interval are given by:
