Final answer:
The question seeks the interval covering the middle 68% of incomes in Town A, but without the mean income or standard deviation, we can't apply the empirical rule. The data provided lists individual incomes, not distribution summaries, meaning we cannot confidently determine the interval with the given options.
Step-by-step explanation:
The student is asking about the interval that covers the middle 68% of incomes for Town A. To answer this, we need to understand the concept of a normal distribution and the empirical rule, which states that approximately 68% of the data falls within one standard deviation of the mean. However, with the given information, there is not enough data to apply the empirical rule directly as we do not have the mean or standard deviation for Town A's income. We might need additional information like the mean income or the standard deviation to accurately answer this question. The intervals provided in options A through D are arbitrary without this context. Nevertheless, if this distribution aligns with the data points provided for individual incomes, we would have the total income listed in a sorted manner (from lowest to highest) that would enable us to approximately determine the middle income range. By looking at the data provided, it seems to represent individual incomes rather than the summary of a distribution that includes mean and standard deviation. As a result, we cannot confidently choose an interval that represents the middle 68% of incomes for Town A from the options provided. Instead, we would need to calculate the total income, average it, and use standard deviation if given, to find the middle 68% incomes.
