14. (3.28) Find the proportion of observations (±0.0001) from a standard Normal distribution that falls in each of the following regions. In each case, sketch a standard Normal curve and sha the area representing the region. (a)z -2.33: (b)-2.33 (c)z 1.55 (d)-2.33 <z<1.55:
Round the correct number of digits! thank you Find the proportion of observations from the standard Normal distribution that are: a) P(Z<-0.12) = b) P(0.41~Z<1.15) - Round to 3 decimal places, Just want final answer, no need to sketch and do NOT convert to percentage.
