Which of the following is an example of a parametric estimate? Group of answer choices We are contracted to build 400 small ships as part of a Navy contract. Based on our previous experience, we estimate that the time to construct ships 100-199 will be 94% of time to complete ships 1-99. A 20,000 square foot hospital addition will cost $4.2 million based on an industry average of $210 per square foot for this type of facility. Three estimators provide their estimates of time and materials cost for a deliverable for our project. Those estimates (and the rationale behind them) are shared with the estimators anonymously for several rounds until the estimates converge. It cost $6,000 to get a small e-commerce site up and running previously, so we will budget $6,000 for construction of another site
