using ''mtcars' dataset which inside R-studio to answer, (must include R-code, visualizations, due comments.)

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.

10. Explain what the term correlation means and what is a correlogram. Find the correlation

between different pairs of attributes in the table. Explain how mpg correlates with hp.

HINT. Try plot-command for the correlograms.
