1. Make a summary of the mtcars -dataset using appropriate methods. 2. Make a histogram showing how cars travel per a gallon. 3. Find the car that has the greatest horsepower. 4. List all tuples where the car has four cylinders. 5. Make a pie chart indicating how the number of cylinders is distributed among the cars. Show another way to visualise the distribution. 6. Explain what the findings are from the scatterplot plot(mpg~hp, data=mtcars). 7. Make a boxplot that shows how the horsepower is distributed and explain the findings from the plot. What is the role of the median value in summary statistics? 8. Show a textual table which shows how the gear-parameter is distributed. 9. Arrange the cars in descending order as to their economy and show the top three cars.
