Following is a contingency table providing a
cross-classification of worldwide reported shark attacks during the
1990s, by country and lethality of attack.
- Find the probability that the attack was Nonfatal
- Find the probability that Brazil reported
- Find the probability that Brazil reported the attack was
Nonfatal
- Find the probability that Brazil reported or the attack was
Nonfatal
- Find the probability that Brazil reported given that the attack
was Nonfatal
- Find the probability that the attach was Nonfatal given that
Brazil reported
- Construct a Relative Frequency Contingency Table, determine
parts (i-vi) again
- Verify your answers obtained from contingency table and
relative frequency contingency table
