Final answer:
The exact percentage of women who are restaurant and foodservice managers is not detailed in the provided information, but statistical methods such as normal distribution can be used to analyze related data.
Step-by-step explanation:
The specific percentage of restaurant and foodservice managers who are women is not provided in the reference information. However, to understand the way data like this is typically analyzed, we can look at the provided example regarding salaries for entry-level managers at a restaurant chain. If salaries are normally distributed with a mean of $44,000 and a standard deviation of $6,500, statistical methods can be applied to estimate various parameters, such as the average salary for a subgroup within this population (e.g., women managers), or to build confidence intervals around mean values, such as the mean number of meals students eat out in a week.
