Answer:
c
Step-by-step explanation:
Given:
The data values are
11, 12, 10, 7, 9, 18
To find:
The median, lowest value, greatest value, lower quartile, upper quartile, interquartile range.
Solution:
We have,
11, 12, 10, 7, 9, 18
Arrange the data values in ascending order.
7, 9, 10, 11, 12, 18
Divide the data in two equal parts.
(7, 9, 10), (11, 12, 18)
Divide each parenthesis in 2 equal parts.
(7), 9, (10), (11), 12, (18)
Now,
Median = 
=
=
Lowest value = 7
Greatest value = 18
Lower quartile = 9
Upper quartile = 12
Interquartile range (IQR) = Upper quartile - Lower quartile
= 12 - 9
= 3
Therefore, median is 10.5, lowest value is 7, greatest value is 18, lower quartile 9, upper quartile 12 and interquartile range is 3.

Answer:
The answer is <u>C.</u> 0.08x + $156.00 = r.
Step-by-step explanation:
Given:
Oprah makes $156.00 per day plus an additional 8% commission on her sales.
She sold x dollars worth.
Now, to find equation how much Oprah made in one day, r.
As. given in question:
She makes per day = $156.00.
Worth of sold = 
Commision on her sales = 8%.
And one day = 
Now, to get the equation Oprah made in one day:






<em>Thus, the equation is</em> 
Therefore, the answer is C. 0.08x + $156.00 = r.
Statistics should be used because the temperature would vary during January and you would want to give an accurate answer.
