Answer 3 & 4
Next let's find the 30th percentile. To do this, we first need to find the width of a new rectangle with the same height, and an area of 0.3. The area to the left of the dotted red line is 0.3. The a value there is the 30th percentile. 436789 10 11 12 13 14 IS 16 17 18 So W. H = Area tells us that W. 12 0.3. Thus W = 3.6 (round to one decimal) Finally, we add the new width to the left hand value of the distribution (5) to get: 30th percentile -
