Hi, i'm david and i'm here to help you and send your question.
00:03
In the question here, we are going to discuss about the hypothesis testing.
00:07
Here in the question i asked me to test the null hypothesis that the mean different between the three designs, a, b, c, d are equal by setting and four equal to the 0105.
00:19
So it means i'm going to test the known hypothesis than the mu a equal to the mu b, equal to the mu c, versus the alternative hypothesis that unlist one means is not equal to the order.
00:39
And now we are given the table under underval, so let me bring up the table here.
00:48
And from the table here, the question i asked me to first identified the f test.
00:54
So the f test statistics equal to the 56 .46.
01:00
And then the next one is going to identify the p value.
01:05
The p value is equal to this one, so it will be approximately to the zero...
