Final answer:
The correct statement is B. The middle 50 percent of the members lost from two to 8.5 lbs.
Step-by-step explanation:
The correct statement in this question is B. The middle 50 percent of the members lost from two to 8.5 lbs.
In Example 6.2, it is mentioned that some doctors believe a person can lose five pounds on average in a month. This provides a point of reference for the weight loss.
Additionally, the information given in Chapter 8 suggests that the weight loss follows a normal distribution with mean equal to 12 pounds and standard deviation equal to three pounds.
Based on this information, the middle 50 percent of weight loss would be from 12 - 1.5(3) = 7.5 pounds to 12 + 1.5(3) = 16.5 pounds.
The student asked about the amount of weight Donna's daughter was told Donna lost. To determine this, we must rely on data provided in the exercise and interpret the relevant statistical measures. In the given information, there is no direct mention of Donna or her daughter; however, we are provided with statistical data regarding weight loss.
Since we are lacking the context of how this data is related to Donna specifically, determining the exact pounds Donna lost is not possible from the given statements (A, B, C, and D). Without additional context or numerical data pertaining to Donna's situation, the question cannot be accurately answered based on the provided excerpts.
