Answer:
IQR = 6
Step-by-step explanation:
Given:
The given set of data is:
40 41 42 43 44 45 46 47 48 49 50
Number of terms,
Therefore, the median is given as term which is the sixth term. Median = 45
(40 41 42 43 44) <u>45</u> (46 47 48 49 50 )
Now, we find the median of the lower half () and upper half (
)of the data that are before and after the median.
The lower half of the data has the values 40 41 <u>42</u> 43 44.
Number of terms are 5. So, median is the third term which is,
The upper half of the data has the values 46 47 <u>48</u> 49 50.
Number of terms are 5. So, median is the third term which is,
Now, IQR is given as the difference of upper half median and lower half median.
First of all, we can simply the first and second equations by and
, respectively, to get
If we subtract the third equation from the first, we already figure out that . The system becomes
so we know as well. Let's plug the values for
and
in any of the three equations to get
So, the solution is ,
