Final answer:
The middle 50 percent of the members lost from two to 8.5 lbs. Doubling the consumption of pasta resulted in a weight gain of 50 pounds. The elasticity of blubber is 16.7.
Step-by-step explanation:
The correct statement is B. The middle 50 percent of the members lost from two to 8.5 lbs.
Doubling your consumption of pasta from 3 pounds to 6 pounds resulted in a weight gain of 50 pounds (from 125 to 175 pounds). To determine the elasticity of blubber, we can divide the change in weight by the change in consumption. In this case, the change in weight is 50 pounds and the change in consumption is 3 pounds, so the elasticity of blubber is 50/3 = 16.7.
Therefore, the correct answer is not provided in the options given. The elasticity of blubber is not represented by any of the choices (A, B, C, or D).
