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
Lets check the interval [Q1-1.5(IQR),Q3+1.5(IQR)],
If any data lies in this interval, it will have no outliers.
[ = [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.

Using the relation between velocity, distance and time, it is found that:
- The rate of the plane in still air is of 140 mph.
- The rate of the wind is of 40 mph.
Velocity is <u>distance divided by time</u>, that is:
A plane traveling with the wind travels 900 miles in 5 hours, hence:
The return trip is against the wind and takes 9 hours, hence:
From the first equation, we have that:
[tex]v_w = 180 - 140 = 40{/tex]
Hence:
- The rate of the plane in still air is of 140 mph.
- The rate of the wind is of 40 mph.
