Explanation / Answer

Please don't hesitate to give a thumbs up in case you are satisfied with the answer.

D. Hi , normal distribution says we are 3 deviations below and above mean at 19 and 44 respectively.

We know for a fact that beyond 3 deviations we have area under curve as .03% .

So answer to the wrong parts is :

Less than 19 and beyond 49 is .03%

Less than 13 is .03%/2 = .015%
