### Understanding Brain Weights Using the Empirical RuleAccording to a study, brain weights of men in country A are normally distributed with a mean of 1.56 kg and a standard deviation of 0.12 kg. By applying the empirical rule (also known as the 68-95-99.7 rule), we can complete the following sentences to better understand the distribution of brain weights.#### (a)Complete the sentence:"Approximately 68% of the men have brain weights between ____ kg and ____ kg."**Answer:**Approximately 68% of the men have brain weights between **1.44 kg** and **1.68 kg**. *(Type integers or decimals. Do not round)*#### (b)Complete the sentence:"Approximately 95% of the men have brain weights between ____ kg and ____ kg."**Answer:**Approximately 95% of the men have brain weights between **1.32 kg** and **1.8 kg**. *(Type integers or decimals. Do not round)*#### (c)Complete the sentence:"Approximately 99.7% of the men have brain weights between ____ kg and ____ kg."**Answer:**Approximately 99.7% of the men have brain weights between **1.2 kg** and **1.92 kg**. *(Type integers or decimals. Do not round)*---### Explanation of Graphs or DiagramsThere are no visible graphs or diagrams within the image. The questions are based on textual completion using the given data and empirical rule context. If diagrams relevant to this topic were present, they might typically include a normal distribution curve illustrating the ranges (±1σ, ±2σ, ±3σ) around the mean.

It is given that the mean is 1.56 and the standard deviation is 0.12.
