Step-by-step explanation:
Set up a proportion with corresponding sides. The two sides marked with a small line in them represent that those sides are equal. Therefore, the side marked 30 is broken into two lines of equal length (each 15).
Thus, we can set up the following proportion:
We can only look up the value in the normal distribution table if the probability of z is LESS than a certain value AND the value is positive.
If the probability of z is MORE than the value, then you need to do 1 minus the probability.
I.e. 1 - 0.93699
[0.93699 is found in the normal distribution table, searching for 1.53]
However, since the value (-1.53) is also negative, you need to do 1 minus AGAIN.
I.e. 1 - 0.93699
Since you have to do both, the answer should be obtained as follows:
1 - (1 - 0.93699) = 0.93699
Sorry for the terrible explanation :/
And apologies if anything is incorrect. Hope this helped though!

Conclusion has nothing to do with math
it is for writing.
