Below provided dataset include some information of a random sample 100 Titanic passengers. Information include; Age, Class traveled: 1st, 2nd or 3rd class, Gender (M/F) and survival status (Yes/No)
We want to see if the average age of the passengers are different across the traveled class (1st, 2nd and 3rd class).
- Write down the null and alternative hypothesis that answers theresearch question.
- Check any assumptions relevant for the above suggested test.
- Ignore the validity of the assumptions; carryout an appropriate test at 5% significance level (include any MINITAB outputs).
- What is theconclusion at 5% significance level?
- Depending on on the decisionin part 4, what other information can you incur about the age and the class they traveled? (Include any relevant MINITAB outputs)
