Answer:
Step-by-step explanation:
Pythagoras of Samos was an ancient Ionian Greek philosopher and the eponymous founder of Pythagoreanism. His political and religious teachings were well known in Magna Graecia and influenced the philosophies of Plato, Aristotle, and, through them, Western philosophy. Wikipedia
Born: Samos, Greece
Died: Metapontum Village, Italy
Full name: Pythagoras of Samos
Children: Arignote, Damo, Telauges, Myia, Aesara, Mnesarchus
Parents: Pythais, Mnesarchus
Siblings: Themistoclea, Tyrrhenus, Eunomus
Given:
(i) The measurements of the data in increasing order are 4,5,6,8,10 and X
(ii) Total number of observations (n) = 6 which is even
(iii) Median = (6 / 7)× Arithmetic Mean
Concept: If there are even number of observations then the median can be calculated as
Median = [(n /2)the term + {(n/2)+1} term] / 2
Here, n = 6,
Median = [(6 /2)the term + {(6/2)+1} term] / 2 = [ 3rd term + 4th term] /2
Median = [ 6 + 8] /2 = 7
Arithmetic Mean (AM) = Sum of the observation / Number of observations
or, = [ 4 + 5 + 6 + 8 + 10 + X] / 6
or, = [33 + X] / 6
According to the problem,
Median = (6 / 7)× AM
or, 7 = ( 6 / 7 ) × ( 33 + X) /6
or, 49 = 33 + X
or, X = 16
Hence, the value of X will 16
