Answer #1
Solution:
The sample mean is 
Mean
= (
x
/ n) )
= ( 55+53+70+54+51+62+65+72+51+57+50 /11 )
=640 /11
=58.181
Mean
= 58.18
Median :
Observations in the ascending order are :
50,51,51,53,54,55,57,62,65,70,72
Here, n=11 is odd
.M= value of (n+1 ) / 2)th observation
= value of (11+12)th observation
= value of 6th observation
=55
Median = 55
Mode :
In the given data, the observation 51 occurs maximum number of
times (2)
∴Z=51
