Assignment 1a: Create a linear regression model and analyze the impact of groove on mileage. Comment about the applicability of this model based on residual plot.
From the residual plot we can infer that the linear regression model cannot be applied for the sample data.
Assignment 1b: Create a linear regression model and analyze the impact of alpha on pluto. Comment about the applicability of this model based on residual plot.
From the above residual plot we can infer that the linear regression model can be applied.
Assignment 2: Using Anova compare the mean comfort level of 3 different kinds of chairs.
As P value is > 0.05 we can conclude that all the 3 chairs provide the same comfort level.
From the residual plot we can infer that the linear regression model cannot be applied for the sample data.
