SIT191 Problem solving task 2 Due: no later than noon Friday 31st August 2018 Total marks: 93 marks Weighting: 10% 2.1 In Australia, 49% of the population have blood type O, 38% have type A,10% have type B and 3% have type AB. Describe how you would use random numbers to represent the four different blood types Use simulation (with at least 10 trials) to estimat people with blood type O and one person with blood type A. nclude the results of all of your trials, as well as the final estimate. a) b) e the number of donors needed to ensure at least three 2+5-7 marks] blel can't tell thenExplanation / Answer
We could use random numbers to assign outcomes for each of the blood types as followed:-
Blood Type O: 0-48
Blood Type A: 49-86
Blood Type B: 87-96
Blood Type AB: 97-99
(b) for simulation trial minimum four persons should be included
trial 1=1,48,7,50 total=4
trial 2=2,8,47,53,97,65 total=6
trial 3=45,22,34,18,60,67,89 total=7
trial 4=19,31,43,7,52,71,89,97,87,90 total=10
trial 5=7,16,23,44,60,72,91,93,95 total=9
trial 6=9,1,11,33,45,85,77,98 total=8
trial 7=4,14,24,34,44,54,64,74,84,94,97 total=11
trial 8=9,18,27,36,45,54,63,72,81,90,99 total=11
trial9=8,16,32,40,64,80,91 total=7
trial 10=5,10,20,45,50,55,65,75,85,95 total=10
final estimate=(4+6+7+10+9+8+11+11+7+10)/10
=83/10
=8.3
approx 8 donors are required
