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

What is the product? (x2+3y+7) [yy+1)
