TASK 4b

Use R to create a table showing the average age of the survivors and the average age of the people who died.

aggregate(Age ~ Survived, data=titanic.df, mean)

##   Survived      Age
## 1        0 30.41530
## 2        1 28.42382

TASK 4c

Use R to run a t-test to test the following hypothesis: The Titanic survivors were younger than the passengers who died.

t.test(Age ~ Survived, data=titanic.df)

## 
##  Welch Two Sample t-test
## 
## data:  Age by Survived
## t = 2.1816, df = 667.56, p-value = 0.02949
## alternative hypothesis: true difference in means is not equal to 0
## 95 percent confidence interval:
##  0.1990628 3.7838912
## sample estimates:
## mean in group 0 mean in group 1 
##        30.41530        28.42382

The p-value obtained is less than 0.05. After looking at the results of the t-test, we conclude that the Titanic survivors were younger than the passengers who died.
