Question

In one trip of the Royal Caribbean cruise ship *Freedom of
the Seas*, 168 of the 698 passengers became ill with Norovirus.
At about the same time, 118 of the 455 passengers on the *Queen
Elizabeth II* cruise ship became ill with Norovirus. Treat the
sample results as simple random samples from large populations.
Test the claim that the rate of Norovirus illness on *Freedom of
the Seas* is less than the rate on the *Queen Elizabeth
II* at the .10 significance level.

The test statistic is:
[ Select ]
["-2.6195", "-0.7168", "-3.1124", "-2.4974",
"-1.1267", "-3.2245", "-0.1157", "-1.3444"]

The range of the P-value is:
[ Select ]
["0.2997", "0.1742", "0.4734", "0.2367", "0.1184",
"0.3115"]

Based on this we:
[ Select ]
["Reject
the null hypothesis", "Fail to reject the null hypothesis"]

**Conclusion** There
[ Select ]
["does", "does not"]
appear to be enough evidence to support the claim that
the rate of Norovirus illness on *Freedom of the Seas*is
less than the rate on the *Queen Elizabeth II*.
