Final answer:
The question and provided statements relate to weight loss rather than weight gain. None of the statements A, B, or C accurately present a mean weight change but instead describe ranges or percentages of individuals. The question's context, dealing with a patient's goal of gaining weight, is not directly addressed by the statistics provided.
Step-by-step explanation:
To determine which outcomes are worded incorrectly in regard to a goal for a patient to gain 10 lbs in body weight over a month, we must first understand what each provided statement is conveying. The given statements seem to be related to weight loss rather than weight gain. Additionally, they need to be correlated with statistical analysis.
Correct statement: Given the choices, we need to determine the one that accurately reflects a scenario or outcome related to the statistic provided. Based on the information from Chapter 8, we have people on a special weight-loss diet with a mean weight loss of 12 pounds, a normal distribution, and a standard deviation of three pounds. Therefore, the correct statement in regards to the mean amount of weight lost is not provided among options A, B, or C, as these options specify individual or group ranges rather than a mean value. Statement D refers to the total amount of weight lost, which requires multiplying the mean by the number of people (15), resulting in a total weight loss of 180 pounds. This seems to be the correct interpretation of the statistics provided.
There isn't a statement that directly communicates the patient's weight gain goal, but since we are discussing statistical outcomes, statement D seems to be the appropriately worded one in terms of presenting statistical data accurately.
Focusing on the special weight-loss diet and the powder vs. liquid diet experiment, the provided information does not offer a precise answer, and we cannot accept the statements about weight loss as they do not pertain to weight gain goals.
