In this problem, that is a standard normal variable and we should determine each of the following probabilities.
00:11
Task c, we should find the probability that that will be between 0 .50 and 0 .84.
00:25
This will be probability that that is less than 0 .84, my most.
00:33
Probability that that is less than 0 .50.
00:39
Now by using that score table, we can find the corresponding probabilities 0 .795 minus 0 .6915.
00:59
And the final value will be 0 .1080.
01:04
Next task d.
01:09
We should find the probability that z will be between minus 0 .84 and minus 0 .5.
01:23
This will be probability that z is less than minus 0 .5 minus probability that that is less than minus 0 .5 minus probability that that is less than minus 0 .84.
01:37
And now by using that score table, the corresponding probabilities will be 0 .3085 minus 0 .2005.
01:53
And the final value is 0 .1080.
02:00
Next, part e, we should find the probability that that will be between minus 0 .30 and 0 .84...
