Solution of this question is we have to test the independency of gender and condiment.
00:09
The significant level given is 10 % 0 .1%.
00:14
So alternative hypothesis is the gender and the gender and condiment are not are not independent.
00:55
Null hypothesis as o, the gender and and condiment are independent.
01:29
The given data, male 15, the given data is male 15.
01:55
This is ketchup, mustard, mustard, ballast or total.
02:12
And here is total 50, 23, 10 and this is 40 .8.
02:29
Female, 25, 19, 19, 8, 50, 2.
02:49
Here is total 40, 18, and this is 100.
03:01
We first calculate the expected values for each cell assuming null hypothesis.
03:10
This is done by taking the product of total of corresponding row and total of the corresponding column.
03:17
This is divided by the grant total.
03:20
So following this we get the following expected table.
03:30
This is expected table here mail, catch up, here mustard, relis and this is total.
04:06
Female.
04:11
Now male.
04:12
Ketchup is 19 .2.
04:17
Mustard 20 .16.
04:20
Rell is 8 .64 and the total is 48...
