<h2>Answer:</h2>
The correct statement about the data set is:
Option: B
(B.)
On arranging the given data points in the increasing order we have:
14 16 19 19 20 20 21 21 22 22 23
- Minimum value of the data set=14
- Maximum value of data set=23
- Median or Middle quartile of data set i.e.
=20
- Lower set of data is:
14 16 19 19 20
Lower quartile or first quartile i.e. =19
- Upper set of data is:
21 21 22 22 23
Upper quartile or third quartile i.e. = 22
- Interquartile range(IQR) is calculated as the difference between the upper and the lower quartile.
i.e.
Hence, IQR=22-19=3
Hence, the correct statement is:
(B.)

<u>ANSWER</u>
<u>EXPLANATION</u>
If we have an exponential expression of the form:
then, the result is a real number, <em>if and only if n is an</em><em> </em><em>odd</em><em> number.</em>
We analyze the options and find out that,the first option is where n is odd, because we have n=7.
Hence the only option that is equivalent to a real number is
The correct choice is A.
