Answer:
To provide a range of values that, with a certain measure of confidence, contains the population parameter of interest.
To provide a range of values that has a certain large probability of containing the population parameter of interest.
Step-by-step explanation:
For estimating a parameter value, it is important to know the statement or degree of confidence that the interval contains the parameter value along with knowing the point estimate and the amount of possible error in the point estimate (which is the interval likely to contain the parameter value).Thus , an interval estimate of a population parameter is the confidence interval with a statement of confidence that the interval contains the parameter value. The confidence interval is a range of values around the statistic that are believed to contain, with a certain probability (say 99%) the true value of that statistic or the population value.
The percentage error is 11.1%
<h3>What is percentage error?</h3>
Percentage error is simply the difference between the exact and the estimated values as a percentage
The given parameters are:
The percentage error is then calculated as:
Evaluate the difference
So, we have:
Hence, the percentage error is 11.1%

Answer:
Yes
Step-by-step explanation:
It not a continues number like 1.33333... therefore it is rational. If it went on forever it would be concidered irrational.
