Task 3 Data analysis
Additionally, you are to analyse the data presented, make clear justification for the statistical test and summarise your analysis (600 words).
Label this task as Task 3 in your assessment submission.
1.      Firstly, a cruise ship from Singapore to the UK carrying 600 people was quarantined for possible infection with a deadly virus. All 600 people were tested for the virus, 150 of these people tested positive for the virus.
I.            Estimate the prevalence of the virus in the people on the cruise ship and provide 95% confidence level for the estimate.

2.      Secondly, 60% of the people on the cruise ship wore protective face mask throughout their time on the ship, 15% of these people tested positive to the virus.
I.            Construct a well labelled two-way table for the data derived from the 600 people on the cruise ship.
II.            Estimate the odds ratio, risk (rate) ratio, risk (rate) difference for those who did not wear face mask on the ship compared to those that wore the face mask.
III.      A statistician performs a 2 test and obtained a p-value of 0.005 on those that wore and those that did not wear the face mask, what does this mean?

Data analysis

3.      Thirdly, face mask is now a very scarce commodity in Singapore, it was suggested that families with higher socio-economic status are more likely to have access to face mask and are more likely to get immediate treatment. Families were grouped into three socio-economic categories.
I.            Which statistical technique to examine the association between the use of face mask and the virus infection while taking the difference in socio-economic status into consideration?
II.            Adjusting for socio-economic status among the people, will the adjusted estimate be closer to the null hypothesis or further from null hypothesis than the unadjusted estimate from 2. (II)? Give explanation for your answer.
