hi. is such a motivating video and very well presented, but i did not understand that 2.33 value. all z values from table 4 and 5 (4- Normal Dist Function, 5- percentage points of the ND) does not have this value. i am new student of this module, there fore my apologize for not being able to read a table ... but i just cant see that value

@crisa81, The number 2.33 is a z-value or is sometime referred to as a z-score. The z-value on a table is usually found using the left column and top row on a Standard Normal Distribution Table. Depending on the type of table you are using, the area associated with a 2.33 z-value should be 0.4901 or 0.9901 if you are using a cumulative z-value table. Hope this helps.
