Question: A manufacturer of of rubber products is trying to decide which "recipe" to use for a particular rubber compound. High tensile strength is desirable. Recipe 1 is cheaper to mix, but he is not sure if its strength is about the same as that of recipe 2. Five batches of rubber were made by each recipe and tested for tensile strength. These are the data collected (in Psi):
Recipe 1 Recipe 2
3067 3200
2730 2777
2840 2633
2913 2044
2789 2834
Which recipe would you recommend and why? (Support your response with evidence)
