Now in this question, we look at, you know, isabel briggs, right, who was pioneering the study of personality types, right? so the personality types are classified into actually four main preferences, right? i prefer main preferences, right? maybe one, two, three, four, something like that, right? then do the question is do merrick carper's choose similar different person types in the midst, right? so to answer this question, you took a sample of 375 battery coppers, right? and then you look at the frequencies for the other carbon, right? so the first one is all of the four personality types are the same.
00:43
You find that you have 34 of these coppers, right? and then you have three of these types, the same.
00:51
The frequency actually is one, two, four.
00:54
And you have two of them the same, then you have one, one seven, or you have one of them being the same, you have 67, or you've got even nine of them been the same, and you've got 33, right? so these are the frequencies for this cases, right? so that's the frequencies.
01:16
So basically you were asked some questions.
01:19
First one is estimate the probability that they will have 0, 1, 2, 3, 4, and the preference in common, right? well, that's simply given by the frequencies, that's simply given by the relative frequencies, right? the frequencies of this divided by total number, right? so for example, for the first case, so i'm just to calculate this, so it's 34 divided by 375, right? 34 divided by 375, right? so that's for the probability here.
01:45
And you do that, you found this to be 34 divided by 375, and you found this, of course, to be 0 .09, right? and for the second case, you can do the same.
01:56
This is 1 -24 divided by 365.
01:59
I find this to be 0 .33, right? and then you also the same 117 divided by 375.
02:09
I guess i get 0 .3 .1...
