Question: 1.Consider the data given in table 4. Augment the data by the dummy variable cooling tower as given in Table 6. a.Build a multiple regression

1.Consider the data given in table 4. Augment the data by the dummy variable "cooling tower" as given in Table 6.

a.Build a multiple regression model to predict ln (C) by taking S and N or their natural logarithms, as well as CT, as the independent variables. Make sure to check for multicollinearity.

b.Use residual analysis and R² to check your model.

c.State which variables are important in predicting the cost of constructing an LWR plant.

d.State a prediction equation that can be used to predict ln(C).

e.Does adding CT improve R²? If so, by what amount?

2. Consider the data in Table 5 once more.

a.Evaluate the correlation between the two scores and state if there seems to be any association between the two.

b.Find the probability of upgrading for each division of the sample by the Bayes' theorem.

c.Find the probability of upgrading for each division of the sample by the nave version of the Bayes' theorem.

d.Compare your results in parts b and c and explain the difference or indifference based on observed probabilities.

Please provide your work in detail and include in-text citations.
