Description

1. Make a Dotplot of the DATA Battery_Life.xlsx:
a. The title “Distribution of Battery Life for 26 Movies Before Color”
b. X Label to units in hours
c. Copy and paste your code (1 pt) and the resultant Dotplot here (1 pt) :
Results:

2. Make a Stem-and_Leaf plot using the file Battery_Life.xlsx:
a. Make a stem-and-leaf plot
b. Copy and paste your code (1 pt) and the resultant Stem-and-Leaf plot here (1 pt) : Results:
3. Make a histogram of the DATA Battery_Life.xlsx that is standard (including left endpoint) with about 5 bars:
a. The title “Distribution of Battery Life for Sample of 20 Batteries”
b. X Label hours
c. Copy and paste your code (1 pt) and the resultant histogram here (1 pt) :
Results:
> hist(Battery_Life$life_hr,breaks=5,right=FALSE,main=”Distribution of Battery Life for Sample of 20 Batteries”,xlab=”Hours”)

4. Make a boxplot (horizontal) of the DATA Battery_Life.xlsx:
a. The title “Distribution of Battery Life for Sample of 20 Batteries”
b. X Label hours
c. Copy and paste your code (1 pt) and the resultant boxplot here (1 pt) :
Results:
>boxplot(Battery_Life$life_hr,horizantal=TRUE,xlab=”Hours”,main=”Distrib ution of Battery Life for Sample of 20 Batteries”)
5. Make a probability plot of the DATA Battery_Life.xlsx with line:
a. The title “Probability Plot of Battery Life for Sample of 20 Batteries”
b. Copy and paste your code (1 pt) and the resultant probability plot here (1 pt) : Results:
> qqnorm(Battery_Life$life_hr,main=”Probability Plot of Battery Life for Sample of 20 Battery”)
> qqline(Battery_Life$life_hr)
