From the given information a sample of one fifty individuals were asked whether or not they supported capital punishment among one fifty people forty individuals said yes sixty individuals said no and remaining fifty individuals said no opinion let us find the expected value for all categories.
00:37
Here there are three categories.
00:40
Hence it can be updated by multiplying 1 by 3 into total number of samples 150 which is equal to 50.
00:52
Therefore the expected frequencies is 50 for all categories.
01:01
This is observed frequency.
01:03
Now let us find oi minus ei the whole square divided by e.
01:11
For the first row it is 40 minus 50 the whole square divided by 50 which is equal to 2 for the second category it is 60 minus 50 divided the numerator part to whole square divided by 50 this is also equal to 2 and and for the third category, it is 50 minus 50, the whole square divided by 50, which is equal to 0.
01:46
Adding this values tends to 4.
01:49
Therefore, kye square statistic, that is summation oi minus ei, the whole square divided by ei, is equal to 4.
02:03
The degrees of freedom can be obtained using the formula k minus 1...
