Hello, let's have a look on the question.
00:02
So, in this question it is given to us that confidence level is equal to 92%.
00:06
Now, since confidence level is 92%, we can find out level of significance which is 1 minus c.
00:12
So, this will be equal to 1 minus 92 divided by 100 which is equal to 1 minus 0 .92.
00:19
So, this value will be equal to 0 .08.
00:22
So, from here we can say that level of significance alpha is equal to 0 .08.
00:27
So, alpha by 2 will be equal to 0 .04.
00:31
Since this is a two -tailed test, we need to find out the value of, critical value of z of alpha by 2...
