In the previous exercise, let p be the probability that the baserunner steals second base successfully. For which values of p would you as manager call for an attempted steal?

Data from previous exercise 

Suppose that a runner for your team is on first base with no outs. You have to decide whether to tell the baserunner to attempt to steal second base. If the steal is successful, there will be a runner on second base and no outs. If the runner is caught stealing, the bases will be empty and there will be one out. Suppose further that the baserunner has a probability of p = .8 of stealing successfully. Does attempting a steal in this circumstance increase or decrease the number of earned runs your team will score this inning?
