Creating a table showing the average age of the survivors and the average age of the people who died.

aggregate(titanic.df$Age,list(Survivors=titanic.df$Survived),mean)
##   Survivors        x
## 1         0 30.41530
## 2         1 28.42382

Running a t-test to test the following hypothesis:“The Titanic survivors were younger than the passengers who died.”

t.test(Age~Survived,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

Thus from the result of this test we can conclude that the titanic survivors were younger than the passengers who died.
