Two popular cruise ships experienced outbreaks of norovirus within two months of each other. Results are shown in the table. Use a 0.05 significance level to find the test statistic and critical value needed to test the claim that getting norovirus is independent of the ship.
Cruise ship A
276 (infected)
1,376 (not infected)
Cruise ship B
338 (infected)
3,485 (not infected)
A.
test statistic = 88.876, critical value = 9.488
B.
test statistic = 71.679, critical value = 9.488
C.
test statistic = 71.679, critical value = 3.841
D.
test statistic = 88.876, critical value = 3.841
