DATA
- There are four variables: Fibre type
- Water absorption (%)
- Soil type
- Fibre content (% by volume)
Part 1
(a) Present appropriate numerical and graphical summaries for each of the variables. Comment on their distributions, and (where appropriate) the presence or absence of any outliers.
(b) Report the 95% confidence interval for the mean water absorption, then use an appropriate hypothesis test to determine whether there is any evidence that the mean water absorption is not equal to 20%. You may assume that the underlying distribution of water absorption is Normal.
(c) Evaluate whether the data is consistent with the claim that the median fibre content is 1.0%. Justify your choice of method.
Part 2
Use appropriate analyses to investigate the relationships between each of the following pairs of variables.
(a) Water absorption and fibre type.
You may assume that the underlying distribution of water absorption is Normal.
(b) Fibre type and soil type.
(c) Water absorption and soil type.
You may assume that the underlying distribution of water absorption is Normal.
(d) Water absorption and fibre content.
Part 3
(a) Determine whether the relationship between water absorption and fibre content varies by fibre type.
(b) Develop a multivariable linear regression model for water absorption, with fibre type, soil type and fibre content as potential predictors. Include all steps of your modelling process and fully justify your choice of final model.
(c) For your final model, explain the effect of each predictor on the outcome variable by interpreting each of the regression coefficients and their p-values.
