Homework Answers
The requirements for drawing conclusions based on R include The plotted data can make any sort of line in a scatter plot
Data must be numerical qualitative:
The data should not be numerical qualitative.
Option (A) is wrong.
The plotted data can make any sort of line in a scatter plot:
Yes, the plotted data can make any sort line in a scatter plot.
Correct Option (B)
There are no outliers in the scatter plot:
the association in a scatter plot should always include a description of the form, direction, and strength of the association, along with the presence of any outliers.
Option (C) is wrong
Option (D) also wrong
The correct choice is Option (B).

USE R STUDIO The stackloss data frame available in R contains 21 observations on four variables taken at a factory where ammonia is converted to nitric acid. The first three variables are Air.Flow, Water.Temp, and Acid.Conc. The fourth variable is stack.loss, which measures the amount of ammonia that escapes before being absorbed. Read the help file for more information about this data frame. - Give a numerical summarization of each column of the dataset, then use boxplots to help illustrating...
