I screwed up the venn diagram, but nailed the malik dice game and the dogs question,
for the question about finding the median height of the boys, i took the 50th value, which was the 4th value in the group 145-150 ( because the first group had 25, second had 29, so it is the fourth)
Then, i did 150-145 = 5, divided by the 29 in the group = 5/29, then i multiplied this by 4 which gave me 0.69, i then added this onto the starting value for the group, so i got around 145.69, how ever i cant remember the class, it might have been 140-145, or 145-150, either way is that the right method? Or did i screw it up? XD Hopefully the grade for an A will be around 54, and i'll get maybe 58ish since i mucked up the venn diagram
