Final answer:
The question lacks sufficient information to determine if a patient will gain 5 pounds in a month. For the group weight loss question, without specific data, no accurate answer can be given. Identifying weight-related statistics (total loss, mean amount, or count) would depend on the specific information asked for.
Step-by-step explanation:
The question "Will a patient achieve a 5-lb weight gain in 1 month?" cannot be answered with the information provided. Thus, the correct answer is D. Insufficient information to determine.
Regarding the correct statement, if it pertains to a group of members who lost weight, without additional context or data, we cannot accurately determine which option is correct. Therefore, we would need more specific information about the members' weight loss results to answer correctly. Assuming the statements are based on a given data set: A might be true if exactly 25% of a group lost two pounds, B might be true if the data shows that the interquartile range of weight loss is from two to 8.5 pounds, and C might be true if the mode of the group's weight loss is within the 3.5 to 4.5 range.
Lastly, when referring to the special weight-loss diet, if we want to know the total weight lost by 15 people, we should choose D. If we're interested in the average weight loss per person, we select C. In this case, B would indicate purely the count of individuals who were on the diet.
