Running Linear Regression Models - Statistics Assignment Help

Assignment Task

Briefly answer the following questions:

Although data subsampling is straightforward, it is often not the best method for creating an independent data set for model testing. Why not?

Traditionally, statisticians have not used resampling techniques when running linear regression models. What is the reasoning behind this?

A researcher has collected noise data at 10,000 locations and provided you with the file “Noise_data.csv”. This contains four variables: an overall measure of noise level called dBA, and noise levels in three frequency bands labelled as Low, Medium and High.

Import the data into R and then do the following:

A. Produce a smooth scatter plot of dBA (the response variable) against Low. Overlay this plot with a red lowess line of span 0.1.
