Question

which of these best describes the shape of the distribution? choose 1 answer: roughly symmetric

Explanation:

To determine the shape of the distribution, we analyze the dot plot. A right - skewed (positively skewed) distribution has a longer tail on the right side. In this dot plot, most of the data points (dots) are concentrated on the left (lower age values: 0 - 3 years), and as we move to the right (higher age values: 4 - 10 years), the number of data points decreases, creating a longer tail on the right. A roughly symmetric distribution would have data evenly distributed around a central point, with similar tails on both sides, which is not the case here. So the distribution is right - skewed (positively skewed). But since the option "Roughly symmetric" is given and maybe there was a partial display, but from the visible data, if we assume the other option was right - skewed, but based on the visible plot, the "Roughly symmetric" is incorrect. Wait, maybe the original problem had another option like "Right - skewed (positively skewed)". But since the user's question shows "Roughly symmetric" as an option and maybe the other option is missing. But from the dot plot, the data is concentrated on the left and tapers off to the right, so it's right - skewed. But if we have to choose from the given (maybe the other option is missing, but assuming the correct one is not "Roughly symmetric", but since the user's question might have a typo, but based on the plot, the distribution is not roughly symmetric. However, if we consider the visible option, but maybe the intended answer is that it's not roughly symmetric, but since the user's question is about the shape, and the dot plot has more data on the left and a long tail on the right, so the correct shape is right - skewed. But since the user's provided option includes "Roughly symmetric" and maybe the other option is missing, but from the plot, the distribution is right - skewed, so "Roughly symmetric" is incorrect. But perhaps the original problem had "Right - skewed" as the correct option.

Answer:

(Assuming the correct option is not "Roughly symmetric", but if we have to choose from the given (maybe a formatting error), but based on the dot plot, the distribution is right - skewed. If the options were, for example, A. Roughly symmetric, B. Right - skewed, then the answer is B. Right - skewed. But since the user's question shows "Roughly symmetric" as an option and maybe the other is missing, but from the plot, the correct description is not roughly symmetric. However, if we follow the given (maybe the user made a typo), but the dot plot's shape is right - skewed. So the answer is not "Roughly symmetric", the correct shape is right - skewed (positively skewed).)

(Note: Since the user's question's option display is partial, but based on the dot plot, the distribution is right - skewed. If the only visible option is "Roughly symmetric", then it's incorrect, and the correct shape is right - skewed.)
