Objective
To investigate by how much and how has the male female ratio changed over the generations? What is the estimated Male Female ratio for the next generation taking in account the last 3 generations?
Description
Contacted 5 persons by visiting their place or talking over phone and collected information about number of males and females in their last three generations DATA TAKEN ON PHONE
(i) Generation I
No. of males=11 No. of females=15
(ii) Generation 2
No. of males=5 No. of females=5
(iii) Generation 3

NO. OF MALES=45 NO. OF FEMALES=43
Probability of males=45/88
=0.51
Probability of females=43/88
=0.48
NO. OF MALES=22 NO. OF FEMALES=22
Probability of males=22/44
=0.5
Probability of females=22/44
=0.50
NO. OF MALES=8 NO. OF FEMALES=5
Probability of males=8/13
=0.62
Probability of females=5/13
=0.37
PROBABILITY OF MALES=0.62+0.05
=0.67
PROBABILITY OF FEMALES=0.37-0.04
=0.33
NOTE:
THIS IS THE ESTIMATED PROBABILITY ACCORDING TO EARLIER GENERATION BUT ACTUALLY THE PROBABILITY OF MALES AND FEMALES IS EXPECTED TO BE EQUAL AFTER FEW YEARS.
