Hello, let's have a look on the question.
00:02
So here we will use normal table.
00:11
For the a part, we need to find out the probability that z is greater than equal to c is equal to 0 .025.
00:19
This is given to us.
00:20
So from normal table, we can see that first the value of c is equal to 1 .96.
00:25
This will be the probability.
00:26
Moving on to the b part, we need to find out probability of mod z is less than equal to c is equal to 0 .95.
00:35
It implies that probability of this can be written as minus c, z and c is equal to 0 .95.
00:44
Or we can write it as, or we can write it as probability, that is 1 minus 2 times probability of z is greater than c is equal to 0 .95.
00:58
The probability that z is greater than c will be equal to 0 .025.
01:02
Again, this is similar as the above one, so c will be equal to 1 .95.
01:07
Next we move on to the c part...
