Okay, first we have this problem a.
00:08
We're trying to get the error between negative zay and positive zay.
00:15
So we wanted this area.
00:18
To get this error, we first calculate this to complementary areas.
00:23
Because of symmetric property, we notice this 1 minus t z, and this is also 1 minus t z.
00:29
So the area between it would be 1 minus 1 minus 2.
00:35
P.
00:35
Z plus 1 minus pz, which is minus 2 minus 2 pz, and this would be 2pz minus 1.
00:46
Then for problem a, we have zay is 1 .96.
00:52
Then pza would be 0 .975 -750.
01:00
Now get the answer would be 0 .95.
01:04
And for problem b, our zay is 2 .33.
01:12
The probability of zay is 0 .9991.
01:17
Then we can get the answer to be 0 .9802.
01:22
So this is the problem for problem a and d...
