Unformatted text preview: constant. When the bins have different widths, count and probability are still similar, but probability density differs. For probability density, the probability is divided by the width of the bin, so that the total area of the rectangles sums to one. Hence, changing the bin width from 0.01 to 1 would sharply cause the height of the histogram to fall. d) Y= Xb+4 Z=3Xb W=3Xb+4 V= W+Y Mean Y: 4.90E+00 Mean Z: 2.70E+00 Mean W: 6.70E+00 Mean V: 1.16E+01 Variance Y: 1.691953 Variance Z: 15.22758 Variance W: 15.22758 Variance V 27.07125...
