Hello students, let's do this question.
00:04
Here, given that, forced statement, and we have to show that the given statement is true or false.
00:09
So first statement is if the null hypothesis is rejected against alternative hypothesis at 5 % level of significance, then using the same data, it must be rejected at 1 % level of significance.
00:27
So the given statement is a false statement because if probability less than 0 .05, it also be greater than 0 .01.
00:41
So it would be rejected with significance level 0 .0.
00:48
It would not be rejected with significance level 0 .01.
00:51
Then next statement is the significance level of a test is probability that null hypothesis is false.
00:59
So here this statement is also false statement because yellow s is the level of significance is the probability of type 1 error.
01:11
Level of significance is equals to probability of type 1 error.
01:18
And we know that type 1 error means probability of reject h0 when h0 is true, that is null hypothesis is true and in the given statement given that null hypothesis is false...
