Hello.
00:03
So we have this table here.
00:07
So what we want to do first is to determine our my hypothesis and alternative hypothesis.
00:21
So let's see.
00:23
So for our non -hypothesis, we're going to say that the frequencies are equal.
00:35
For our alternative hypotheses, frequencies are not equal.
00:58
Are not equal.
01:03
So we can see that we have six categories, if you like.
01:10
So the number of degrees of freedom and the k minus 1, 6 minus 1 and we have 5.
01:26
So we're going to be using the k squared table or the kai squared distribution for the probability of 1, uh 0 .1.
01:37
I was given in a question at 0 .1 significance level okay and 5 degrees of freedom.
01:46
So the kai square value the kai square value at 0 .1 significantity level and degree of freedom of 5 that's going to give 9 .2 36 now let's look at the uh expected frequency.
02:14
So the expected frequency.
02:23
So in the equation we've been told that the die is row 30 times.
02:28
So the expected frequency is just going to be 30 divided by 6.
02:34
And that is 5.
02:41
So now let's look at the test statistic.
02:43
That's summation, if not minus e...
