Answer:
Data : $436, $403, $479, and $249 .
[tex]Mean = \frac{\text{Sum of all observations }}{\text{total no. of observations}}[/tex]
[tex]Mean = \frac{436+403+479+249}{4}[/tex]
[tex]Mean = 391.75[/tex]
No. of terms n = 4 (even)
Median = [tex]\frac{\frac{n}{2}th +(\frac{n}{2} +1)th}{2}[/tex]
Median = [tex]\frac{\frac{4}{2}th +(\frac{4}{2} +1)th}{2}[/tex]
Median = [tex]\frac{2nd +(3)rd}{2}[/tex]
Median = [tex]\frac{403+479}{2}[/tex]
Median = [tex]441[/tex]
Mode is the value repeating the more no. of times
So, there is no mode.
Hence Mean is 391.75 , Median is 441 and no mode.
