In R, using the lme4 package, we can call this data set with the command:

data(Arabidopsis). Access "Package 'lme4,'" to retrieve data on genetic variation in responses to fertilization and simulated herbivory in Arabidopsis. This data set can be used with the command: data(Arabidopsis). Using the lme4 package:

1. Establish with argument what effects there are, and whether they are random or fixed. Use the "lmer" function to then fit your proposed model to the data. Provide residual plots and statistical conclusions regarding extrapolating this model to other data points.

(Problem 1): A mixed linear effects model was fit using the "lme4" package in R. Required plots were given and correct conclusions drawn.

(Problem 1): Required plots were given

(Problem 1): Mathematically rigorous conclusions were drawn.

(Problem 2): Correct explanations given for all the parameters.

(Problem 3): The correct answer was given with examples which assist in it being correct.
