Question: based on the cost of obtaining the sample information and...

Question details

Based on the cost of obtaining the sample information and its efficiency, is it worth obtaining it? Why? Please include ALL the relevant information for this decision and use specific numbers. Your answer must discuss EVSI, net EVSI (The EVSI minus the cost of the SI), the Efficiency of the Sample Information (abbreviated "E") and the Risk Profile.
