4. a (R Problem) Using R. solve the following problem: The following data give the length (in cm) of 12 gentoo penguins and 12 chinstrap penguins. Gentoo 76.9. 84.2. 78.0. 78.1. 80.8. 78.2. 81.8. 82.1. 80.8. 75.7. 83.5. 78.6 Chinstrap 76.2. 76.3. 75.5. 75.9. 76.5. 73.1. 73.8. 76.3. 74.9. 76.3. 76.8. 75.7 a) Input this dataset into R as two vectors. Find the ve number summary for each group. b) Construct the histogram for each group (using at least 6 bins). 'What do you observe on the shape of the data distribution in each group? 0) Construct the side-by-side boxplots for the above two groups. For each group. describe the data distribution in shape. central tendency. and dispersion. Are there any outliers
