With a big points!
an office manager recorded the number of reams of paper that were used for a printer each month for six months: 15, 10, 25, 19, 10, 17.
(a) identify the five-number summary of the data set.
(b) draw the box-and-whisker plot.
(c) compute the standard deviation. show all your work.

Part (a)

Mean = 

Range = 25 - 10 = 15

Median,  = 16 (Refer to the first picture)

Lower Quartile,  = 10

Upper Quartile,  = 22

Interquartile Range, IQR = 

Part (b)

The box plot is shown in the second picture below

Part (c)

Mean = 16

Subtracting 16 from each data value, find sum of the square of each answer and divide by 6




Standard deviation =  (rounded to 2 dp)

The correct answer is addition
