The median class interval is 20-30 and the number of observation less than 20 is 45.then the frequency of the middle class is?

Answer 1

Answer:

median of 100 observation grouped in classes of equal width is 25.

The median class interval is 20-30 and the number of observation less than 20 is 45.then the frequency of the middle class

average of five observation X1,X2,X3,X4 and X5 is 24. The average of first three observation is 10 less than the average of last three observation if the average of first two observation is 16.5, what is the value of the third observationmedian of 100 observation grouped in classes of equal width is 25.

The median class interval is 20-30 and the number of observation less than 20 is 45.then the frequency of the middle class.
