## Statistical Analysis for Helmet Design### Understanding Head DimensionsEngineers must consider the breadths of male heads when designing helmets. The company researchers have determined that the population of potential clientele have head breadths that are normally distributed with a **mean of 6.9 inches** and a **standard deviation of 0.9 inches**.---### Determining the Range for Most Head Breadths**Question:** In what range would you expect to find the middle 68% of most head breadths?**Answer:**- Between **[input box]** and **[input box]** inches.---### Sampling from the Population**Question:** If you were to draw samples of size 54 from this population, in what range would you expect to find the middle 68% of most averages for the breadths of male heads in the sample?**Answer:**- Between **[input box]** and **[input box]** inches.---**Note:** Enter your answers as numbers. Your answers should be accurate to two decimal places.In this exercise, understanding the principles of normal distribution and the empirical rule (68-95-99.7 rule) is crucial in determining the range for head breadth measurements.
