Lecture 1b Errors

[mobatmedia]

On Slide 57, in the table's third row (n=1), (y-y^)**2=36, not 64, so C(4,2)=108, not 136. On Slides 63, in the table's sum row the total is 14, not 13, so C(3,0)=14, not 13. On Slide 67, the table's sum is incorrectly labeled C(2,0) instead of C(4,0), the table's sum row the total is 48, not 54, and so C(w4,b4)=48, not 104. On Slide 73, in the table's third row (n=1), y=15.05, not 15.01, so (y-y^)**2=0.9025, not 0.91, in the table's fourth row (n=2), y=18.06, not 18.01, so (y-y^)**2=3.7636, not 3.96, and the table's sum is 13.7262, not 12.82. Since C(3,0)=14 not 13 (see above), the slide's conclusion is still correct.
