TASK 4a: Reading the data from the csv file and viewing it

TitanicAnalysis.df <- read.csv(paste("Titanic Data.csv"))
View(TitanicAnalysis.df)

TASK 4b: Create a table showing the average age of the survivors and the average age of the people who died

Titanic <- aggregate(Age~Survived,data = TitanicAnalysis.df,mean)
Titanic
##   Survived      Age
## 1        0 30.41530
## 2        1 28.42382

TASK 4c: run a t-test to test the following hypothesis:

H2: The Titanic survivors were younger than the passengers who died

t.test(Age~Survived,data = TitanicAnalysis.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

Since p<0.05 we reject null hypothesis and hence the survivors were younger than those who died.
