Answer 1

Please use R to read in data as a vector.

data is read into a vector x

> x=c(5,5,10,8,7,1,6,2,8,7,12,13)
> x
[1] 5 5 10 8 7 1 6 2 8 7 12 13

h-i) Report the summary from the R output.
> summary(x)
Min. 1st Qu. Median Mean 3rd Qu. Max.
1.0 5.0 7.0 7.0 8.5 13.0

h-ii) Using R, draw the boxplot of this data (you may use boxplot( ) command). Include the R code and the resulting boxplot in your answer.
