According to the problem, we have to calculate the expected frequency for each cell.
00:06
Ok, and that cells and all data is given in the problem.
00:10
So, formula for expected frequency is rho total is rho total into column total into column total divided by grand total that grand total.
00:36
So, we will make a table for each cell.
00:39
So, according to the columns, we have to find the value of column 1 cells, value of column 2 and value of column 3.
00:56
So, there are rows are given.
01:00
So, there are first row and there is second row.
01:06
So, we have to find for first cell the effective or the expected frequency.
01:13
Ok, so the expected frequency for first cell is the rho total.
01:20
The rho total is 85 into the column total is 55 divided by the grand total is 155.
01:29
So, for first cell expected frequency is 30 .16.
01:37
For column 2 and for this cell, the expected frequency is rho total is 85 into column total is 40 divided by grand total is 155.
01:57
So, expected frequency is 21 .93.
02:02
For this cell, the expected frequency is 85 into column total is 60 divided by grand total is 155.
02:13
Ok, so the expected frequency is 32 .90...
