Final answer:
The specific percentages of women working in each company and in management positions cannot be determined without detailed company data. However, there is an upward trend in the participation of women in the workforce and higher education, which is slowly influencing the presence of women in management roles.
Step-by-step explanation:
To calculate the percentage of women working in each company and the percentage of management jobs held by women, we would need specific data for each company, which isn't provided in the question. However, based on the general information provided, it's evident that there has been a significant increase in the number of women participating in the workforce and in higher education, which has impacted the dynamics of women in management roles over the years.
For instance, we know that the workforce participation of adult women rose to 58.1% by 2014, and the number of women in higher education also increased, with women receiving 56% of bachelor's degrees by the same year. The occupational choices and progress in educational attainments have played a role in reducing the gender wage gap and potentially affecting the distribution of women in management positions.
Specific percentages of women in management in the provided companies would require detailed data. Nevertheless, the information illustrates a trend towards greater equality, albeit discrepancies in high-level positions persist.
