Answer:
First option, incorrect....
Step-by-step explanation:
This is because the interval is either below or above 26.8 by 0.6
-+ means
26.8 + 0.6 = 27.4
26.8 - 0.6 = 26.2
The confidence interval % can change
- The second option states 28 but that is not in the interval
- The third option is somewhat right but the parameter should be emphasized how confident you are
- The last option is wrong since it has the word "every young" when the initial sentence was the mean
