Answer:
Example: the median is not affected by very large or very small values (outliers).
Step-by-step explanation:
Suppose my income for 5 months is $1000, $1500, $1550, $2000, $90,000. (I hit the lottery in the last month!).
The median is the number in the middle: $1550. That $90,000 would increase the <u>mean</u> ("average") by a lot, but the median is unchanged.
If a newspaper story reports the median house price in a neighborhood is $93,000, that million dollar mansion on the corner won't change the median. Half the prices are less than $93,000 and half are greater.

It will take her 5 5/8 hours to read 3/4 of the book
<h3>Ratio and proportions</h3>
Given that Elisabeth reads 1/5 of her book in 1 1/2 hours, this is expessed as:
0.2 of a book = 1.5 hours
In order to determine the time taken to read 0.75 part of the book, we will have:
0.75 of a book = x
Take the ratios
0.2/0.75 = 1.5/x
0.2x = 1.125
x = 1.125/0.2
x = 5.625
Hence it will take her 5 5/8 hours to read 3/4 of the book

Answer:
D. 0.857
Step-by-step explanation:
The coefficient of determination, R-squared, is simply the square of the correlation coefficient;
R-squared = r^2
R-squared = 0.926^2
R-squared = 0.857
Therefore, the coefficient of determination is 0.857.
