Individuals between the ages of 0 and 12 had a survival rate of 56.04% and were the most likely age group to survive. Individuals between the ages of 60 and 72 had a survival rate of 27.03% and were the least likely age group to survive

b) Null hypothesis: Survival rate is independent of age

Alternative hypothesis: Survival rate is dependent on age.

Chi-square value: 18.650023

Distribution of the test statistic under the null hypothesis: Chi-square with df of 6

P value:0.0048

Conclusion: The null hypothesis can be rejected because the p value is less than the alpha level of 0.01. This means that the survival rate is dependent on age.
