2 39 A Density Curve Looks Like An Inverted Letter V The First Segment Goes From The Point 0 0 6 To The Point 0 5 1 (37.86 KiB) Viewed 87 times

2.39 A density curve looks like an inverted letter "V." The first segment goes from the point (0,0.6) to the point (0.5, 1.4). The second segment goes from (0.5, 1.4) to (1,0.6). I (a) Sketch the curve. Verify that the area under the curve is 1, so that it is a valid density curve. (b) Determine the median. Mark the median and the approximate loca- tions of the quartiles Q and Q3 on your sketch. (c) What percent of the observations lie below 0.3? (d) What percent of the observations lie between 0.3 and 0.7?
