Answer:
The median is the best measure of center for distributions C and D.
Step-by-step explanation:
The <u>median</u> is the best measure of center for skewed distributions or distributions with outliers because it is a <u><em>robust</em></u> statistic, meaning that outliers and skewed data have <em>little effect </em>on the median.
Meanwhile, the <u>mean</u> is a good measure of center for symmetric distributions since it is <u><em>non-robust</em></u>.
Answer A has a roughly symmetric distribution, and answer B has a uniform distribution.
Answer C has a left-skewed distribution, and answer D seems to have a right-skewed distribution (since the right tail is longer than the left tail).
Therefore, the <u>median</u> would be the <u><em>best measure of center</em></u> for choices C and D.
Answer:
The amount after 1 year is $ 1060 .
Step-by-step explanation:
The amount after 1 year on $1,000 invested at 6% per year on simple interest
is given by,
$ 
= $ (1000 + 60)
= $ 1060
We know that, if,
Principal = P unit
Rate of annual simple interest = R%
Time = T year
then, amount, A =
unit
