Question

3.    The following table shows the blood alcohol level and respective ages of people who died in an automobile accident on I-95 (fictional data)
For clarity, columns and rows are re-labeled A-C and D-G
		Blood Alcohol Level of Victim
		A	B	C
		0%	0.01-0.09%	>10%	TOTAL
D	0-19	142	7	6	155
E	20-39	47	8	41	96
F	40-59	29	8	77	114
G	>60	47	7	35	89
	TOTAL	265	30	159	454

1. From the table, identify at least two independent events
2. From the table, identify at least two event that intersect
3. How many victims were in the category described by?
   1. (A and A’)
   2. (C or F)
   3. (A’ and G’)
   4. (B or G’)
   5. P(A or D)
   6. P(B or F)
   7. P(C or G)
   8. P(B or C or G)
   1. Calculate the conditional probability of C, given each age category, that is, P(C|D), P(C|E), P(C|F) and P(C|G)
   10. Compare these probabilities and formulate a hypothesis as to which age groups seems more likely than others to have a blood level at least 0.10% blood alcohol volume.
