When recording audio, please move your microphone farther away from your mouth, and maybe off to the side (i.e. not directly in line with/in front of your mouth). The sounds of lip smacking / saliva in the mouth are *very* noticeable (and distracting) in this video. This can be the result of having the mic too close to the mouth, picking up and amplifying every tiny little sound. Adjust the gain or other settings to compensate for the increased distance of the microphone. Otherwise, good video!
is it possible to find/calculate by hand the z-score when the area/probability is given? and when it is interpolated between two numbers (eg. find z value when area is 0.490, i'm sure it's 2.326) if so, how?
@delayedmuffin its just a made up observation....In this case it took the pizza man 21 minutes to deliver the pizza whereas it takes him 25 minutes on average to do so. To understand how standard deviation works in this problem - the standard deviation of the pizza man's usual delivery time is 2 minutes.
@delayedmuffin Meaning that he generally arrives 2 minutes earlier than his average of 25 minutes OR 2 minutes later than his avearge. So one standard deviation is 23-27 minutes. In this trip it took him 21 minutes to get there. The z-score calculates how many standard deviations this particular trip took him to deliver the goods. Two standar deviations in this case equals 4 minutes plus or minus from 25.

This is truly statistics made simple. However, if one of the variables is missing, can the z score still be calculated?

Where did the 21 come from? It is the 2 multiplied by 2 to get
-4, couldn't 4
