 Hello and welcome to the session. In this session, we will discuss a question that says that suppose 800 people are surveyed, the table shows the results of the opinion of males and females on an environmental board issue. And here we have given the joint and marginally related frequency table. Now here in the first part we have to find that out of 800 people surveyed, what percent are males and females. And in the second part we have to find what percent of people are for and against the bond issue. Now let us start with the solution of the given question. Now in this table we are given two categories, one is gender that is male and female and other is opinion that is for and against the bond issue. And in this table we are given the joint and marginally related frequencies. Also here we are given male and female in rows and for against in columns. Now in row one see the cell corresponding to male and total which is 0.75 is the marginally related frequency for males which tells the proportion of males in the survey. Now when we multiply the proportion by 100 we get the required percentage. So percentage of males in survey is equal to 0.75 into 100 which is equal to 75%. Similarly in row two see the cell corresponding to females and total and it is 0.25 so marginally related frequency for females is 0.25. Now this marginally related frequency gives us the proportion of females in the survey so percentage of females in the survey is equal to 0.25 into 100 which is equal to 25%. Now we have to find the proportion of people for the bond issue. Now people include both male and female for this we see column and here marginally frequency that is marginally related frequency is 0.76. So required percentage is equal to 0.76 into 100 which is equal to 76%. So percentage of people for the bond issue is equal to 76%. Also the marginally related frequency in column two is 0.24 so percentage of people against the bond issue is equal to 0.24 into 100 which is equal to 24%. So percentage of males in the survey is equal to 75% percentage of females in this survey is 25% when percentage of people for the bond issue is 76% and percentage of people against the bond issue is 24%. So this is the solution of the given question that's all for this session hope you all have enjoyed this session.
