Hi, i'm david and i'm here to help you answer your question.
00:04
Now let me bring up your question here.
00:07
In this question here, we're going to discuss about the standard normal curve and we want to use the calculator to find the shaded region in the part 1 to the part 4.
00:20
In the part 1, once you find the area to the left of the minus 2 .31.
00:26
Now it will use the calculator and then you input this value here.
00:31
Is 2 .31 and then we get the answer equal to the 0 .104.
00:38
So this one will be the 0 .1 0 .0.
00:43
So 0 .0 .0 4.
00:47
And that's going to be the answer for the part 1.
00:50
For the part 2, we have the area will be on the right of the 0 .72.
00:56
So if we use the calculator, we get this one equal to the 0 .2.
01:03
So 0 .2358...
