We want to study project completion time (y) as a function of resources (measured, say, by the number of people hours worked) but also take into account the impact of robots (1 or 0 for presence or absence of robots) 1. What would be the complete second order model? 2. How would you determine whether the rate of improvement in project completion time due to resources depends on the presence of robots? Please explain your reasoning and the test procedure you would follow. 3. For a given number of hours worked, how would you determine if the project completion time differs with or without robots? Please explain your reasoning and the test procedure you would follow.
