So, in the given question, here we have been provided a scenario.
00:07
So, first part of the question says that what test would be used for the analysis of the given data.
00:12
Now, in the for the given data, we are we will be using one way anova, right, because there are more than two populations in this case.
00:23
Next part here, the result for the given hypothesis test, the test statistic value is provided to us, right.
00:30
Now, here, okay, so i will just take the null hypothesis here will be that the mean of the three are equal and alternative is that at least one of the group means are different, right.
00:51
So, here we have the test statistic value is provided to us as 4 .750.
00:59
Now, first of all, we need to determine the degrees of freedom.
01:04
So, our degrees of freedom for the numerator, this is 4 minus 1, so k here is equal to 4, this is 3 and the degrees of freedom for the denominator, this is n minus k that is equal to this is 3 by 15 minus 4.
01:25
So, this is equal to 41, right.
01:28
So, the critical value here for the given degrees of freedom and alpha 0 .05 is equal to 2 .833, right.

Now, third part is the finding significance...
