Let's solve this question.
00:01
In this question, we can say that here the null hypothesis h0 such that the people claiming to be affected emotionally by a social media is same as provided in this study.
00:39
And here the alternative hypothesis h is such that the people claiming to be affected emotionally by the social media is different as provided in the study.
01:19
Now here we know that the expected value that is equals to the sum of total in the row multiplied by the column total or we can say the sum of column that will be divided by the grand total.
01:45
So here we will get its generation.
01:51
Here it is observed frequency and here it is expected frequency.
01:56
So here the generation z, then it is millennials, here it is generation x and here it is baby boomers.
02:08
So here we will get 279, 201, 103 and 17.
02:19
So here we can say that the total that is 600.
02:23
Now here we will get the expected frequency that is 264, 192, 114 and 30...
