Question: A windmill is used to generate direct current. Data are collected on 45 different days to determine the relationship between wind speed in mi/h (x)

A windmill is used to generate direct current. Data are collected on 45 different days to determine the relationship between wind speed in mi/h (x) and current in kA (y). The data are presented in the following table.

a. Compute the least-squares line for predicting y from x. Make a plot of residuals versus fitted values.
b. Compute the least-squares line for predicting y from ln x. Make a plot of residuals versus fitted values.
c. Compute the least-squares line for predicting ln y from x. Make a plot of residuals versus fitted values.
