Is an extreme observation necessarily an outlier? Explain your answer.Choose the correct answer below.A. Yes, extreme values are always outliers. When using a boxplot to identify outliers, the upper and lower fences are specifically constructed to find the outliers.B. No, extreme values are never outliers. Outliers are values that appear many times more than other values in the data set.C. No, it is only a potential outlier. Whether or not it is truly an outlier depends on whether it is much greater or much less than the other values in the data set.D. No, it is only a potential outlier. Further data analyses are necessary to determine if it is truly an outlier.

Confidence Intervals

When we calculate intervals in probability and statistics, it can be simply termed as finding out a confidence interval. The confidence interval is usually calculated from the data set which is observed. The value of the parameter that needs to be calculated is present here only.
