Suppose you are given an undirected graph with associated edge costs which are all positive and distinct and let be a shortest-path from node to node in . Now replace all edge costs by a new cost , thereby creating a new instance of the problem with the same graph set of nodes and set of edges but modified edge costs. Select all options below where would still be guaranteed to be a shortest path from to in this new instance of the graph (with modified edge costs ): Select all that apply.

Evaluating the Effect of Different Coatings on Corrosion Resistance: We are considering three different coatings for corrosion resistance. The final decision regarding which coating to use will be made by the management on a number of different factors, which include cost, availability and contract negotiations, quality of coating, and others. For our part, we have been asked to test these using ultrasonic thickness to measure material loss. After a carefully controlled experiment, the data returned the results from our provided dataset. Please provide a complete analysis plan for analysis of the corrosion based on this data, so that management can take this into account in their decision-making process. you are not required to complete the analysis, rather, you must articulate which steps you would take to complete the analysis.
