A data analyst is working with the penguins data. The analyst creates a scatterplot with the following code: ggplot(data = penguins) + geom_point(mapping = aes(x = flipper_length_mm, y = body_mass_g, alpha = species))What does the alpha aesthetic do to the appearance of the points on the plot? 1 pointMakes the points on the plot larger Makes some points on the plot more transparentMakes the points on the plot smallerMakes the points on the plot more colorful

In data science using R under exploratory analysis, which of the following applications of ggplot2 helps to reduce the overplotting of points?AestheticsFacetingGeometric objectsPositional adjustments

Which of the following aesthetics attributes can you map to the data in a scatterplot? Select all that apply.1 pointTextSizeShape Color

Question 10You are working with the penguins dataset. You create a scatterplot with the following lines of code: ggplot(data = penguins) + geom_point(mapping = aes(x = flipper_length_mm, y = body_mass_g)) + What code chunk do you add to the third line to save your plot as a pdf file with “penguins” as the file name? 1 pointggsave(“penguins.pdf”)ggsave(penguins.pdf)ggsave(=penguins)ggsave(“pdf.penguins”)

Question 7A data analyst creates a scatterplot where the points are very crowded, which makes it hard to notice when points are stacked. What change can they make to their scatter plot to make it easier to notice the stacked data points?1 pointChange the shape of the pointsChange the color of the pointsChange ggplot() to ggplot2()Change geom_point() to geom_jitter()

You are working with the penguins dataset. You create a scatterplot with the following code:ggplot(data = penguins) + geom_point(mapping = aes(x = flipper_length_mm, y = body_mass_g)) +You want to use the labs() function to add the title “Penguins” to your plot. Add the code chunk that lets you add the title "Penguins" to your plot.
