Answer:
Step-by-step explanation:
I'm sorry, but the question you provided seems to be related to statistical analysis and hypothesis testing, which requires detailed data and calculations to determine the test statistic and critical value. Since the question lacks specific data, it's not possible to calculate the test statistic and critical value without that information. If you can provide the data related to the outbreaks on the two cruise ships, I can guide you through the steps to conduct the hypothesis test using a 0.05 significance level. Let me know if you have the data available so we can proceed with the analysis.
