Question
The data in the accompanying table is from observing the count of bacteria. The COUNT (Y) is
recorded in 1000's of a BACTERIA (X₁) and the growth rate, RATE (X₂) of a type of bacteria.
Below is the data set to be used for analysis.
Y COUNT

2.1. Change the dataset into a usable format for modelling.
2.2. The analyst created plots that have the following shapes. Below for example, the first plot is
simply fitting a regression with say only bacteria B and its growth rate and the second plot is a
residual plot.
X₂ RATE
0.15
014
0.08
0.12
0.16
0.01
He then realises that a multiple regression of the first order will not fit the data appropriately.
2.2.1. Provide the regression model, the regression function and the estimator (response function)
for the model that he should use to fit the data. Provide the name of such a regression model
and point out the problems that can arise with these types of regression models. [Do not
forget to centre]
2.2.2. Show the amended dataset to be used.
2.2.3. Refer to dataset in Question 2.1. The following response function is what was initially
determined
E{Y} = Bo + B₁X₁ + B₂X₂ + B3X3.
Find the response function for Bacteria A.
