The variable Experience measures months of administrator experience and the variable Training measures the number of relevant training credits. The variable Completed captures whether administrator completed a set of tasks or not.

1. Create plots to explore the variables that seem to explain administrators ability to complete a set of tasks. Comment on the results.

2. Based on the model, estimate a model that can explain administrators ability to complete a set of tasks. Use the entire dataset for prediction. Comment on the model output and the results.

3. Among those who completed the task, what is the percentage of administrators incorrectly classified as failing to complete the task?

4. How much experience must be accumulated by an administrator with four units of training before the estimated probability of completing the task exceeds 0.5 for the administrator?
