Hi, i'm david and i'm here to help you answer your question.
00:03
Now let me bring up your question here.
00:06
In the question here, we are going to discuss about the hypothesis testing.
00:10
Here we want to test the noon hypothesis when the mean would be greater equal to the 10 versus the alternative hypothesis, then the mean would be smaller than the 100 here, sorry.
00:24
And the question tells us then the data here and the question i asked us to find, the mean and the standard division.
00:33
So x -par and the s also need to find the n as well.
00:37
So if we counted 1, 2, 3, 4, 5, 6, so n equal to the 6.
00:42
Let me pass the data into the calculator, 95, 99, 85, 80, 98, and 97.
00:52
And we have the x -par equal to the 92 -pong.
00:56
I wrote the answer to the 2 decimal pluses will be the 3 -3.
00:59
And we given the s equal to the 7 .89 and that's going to be the answer for the a...
