Answer:

There is one outlier that indicates an unusually small number of assignments required in that class.

Step-by-step explanation:

Arranging the data is ascending order, we get:

4, 15, 15, 16, 17, 18, 20, 21, 22, 23, 23, 23, 24, 25

Lets divide the data in 4 equal parts to know the IQ ranges.

(4, 15, 15), 16, (17, 18, 20), (21, 22, 23), 23, (23, 24, 25)`

We can see that first interquartile range Q1 is 16

The third interquartile range Q3 is 23.

The IQR is 23-16=7

Lets check the interval [Q1-1.5(IQR),Q3+1.5(IQR)],

If any data lies in this interval, it will have no outliers.

[[16-1.5(7),23+1.5(7)] = [5.5,33.5]

So, we can see that all the data except 4 lie in the interval [5.5,33.5].

Therefore, we can say that -

B - There is one outlier that indicates an unusually small number of assignments required in that class.

Ok, first you need to read a - g and mark down the information you know. Also, this continuous function can look pretty much like anything long as it has the a - g constraints/rule. 

A) We know the domain(x values) is between -10 to infinity
(-10,-9,-8,-7,-6,-5,-4,-3-,2,-1,0,1,2,3,4,5,6,7,8,9,10, to ---------> infinity)
B) We know the range(y values) is between -6 to infinity
(-6,-5,-4,-3-,2,-1,01,2,3,4,5,6,7,8,9,10, to ---------> infinity) 

C) Next we know f(0) = f(4) = 0
So we know when x = 0  that f(0) = 0 or we can say  y = 0. We also know when f(4) = 0 so when x = 4 y = 0. So we have two points (0,0) and (4,0) that our function will be on so plot the two points (0,0) (4,0)

D) It tells us that f(x) (y) is increasing between the x values (-10,-6)  or (-2,2) or (4, to infinity)

E) It tells us that f(x) (y) is decreasing between the x values (-6,-2) or between (2,4)

F) Tells us that f(x) (y) is greater than or equal to between the x values of [-8,-4] or between the x values [0, to infinity) so this lets us know our drawing is going to be above or equal to 0 when we are in the values [-8,-4] or [0, to infinity)

G) Tells us that f(x) (y) is less than 0 when the function / drawing is between the x values of (-10, -8) or (-4,0)  

The picture is what the function could look like. It can be different but needs to following the rules that are given
