Chicken Weight

1. Create a simple scatter plot with the variable "feed" on the x-axis and "weight" on the y-axis for the data saved in object "chickwts". Some points in your scatter plot may be printed over other points so that you cannot see that there are multiple points. Make your points translucent.

glimpse(chickwts) ## Rows: 71 ## Columns: 2 ##

$ weight 179, 160, 136, 227, 217, 168, 108, 124, 143, 140, 309, 229, 181~ ##

$ feed horsebean, horsebean, horsebean, horsebean, horsebean, horsebea~

2. Create a boxplot for weight for each feed type in the same figure. 3. Create a set of simple density plots for weight with a separate density for each feed type.

4. Replicate the figure below as good as you can.

5. Does the chicken weight differ for different types of feed? Use a statistical test to answer this question. Verify that all assumptions of your chosen test are met by the data.
