(b) $6.8$

(c) $8.8$

(d) $16.8$

(e) $68$

Step-by-Step Solution

Answer

The correct option is (a)$0.68$

Step 1: Given information

Alaska is the lowest outlier in this question.

Step 2: Concept

An outlier is a value that is notably different from other values in a random sampling of the population.

Step 3: Explanation

An outlier is a value that is out of the ordinary in comparison to other values in a random sample of the population. Potential outliers are distinct from the broader patterns; they do not appear to be isolated from the rest of the distribution. Alaska is an outlier in this case, thus it must represent the distribution's minimal value. The percentage of Alaskans aged $65$ and up is $0.68$
