Final answer:
The weight of an organ in adult males does not have a bell-shaped distribution with a mean of 350 grams.
Step-by-step explanation:
The statement is false. A bell-shaped distribution, also known as a normal distribution, is characterized by a symmetrical curve with the majority of data points clustering around the mean. The mean represents the center of the distribution, while the standard deviation describes the spread or variability of the data. In this case, the weight of an organ in adult males follows a bell-shaped distribution with a mean of 350 grams. Therefore, the statement is false.
