Thank you for the opportunity to help you with your question!
The ratio of men to women is 6:5 or 6/11 or 156 men
6/11= 156
1=?
= 1*156*11/6=286
hence the total number of employees is 286 made up of 156 men and 130 women

Is the following conclusion drawn after finding that there is a significant correlation between annual personal income and years of education true?Conclusion: More education causes a person's income to rise. The conclusion cannot be drawn because correlation does not necessary implies causality. The conclusion is correct since the correlation is significant. The conclusion is incorrect; Instead we should conclude that annual personal income increases more years of education.

<p>Conclusion: More education causes a person's income to rise.</p>
Is the following conclusion drawn after finding that there is a significant correlation between annual personal income and years of education true?Conclusion: More education causes a person's income to rise. The conclusion cannot be drawn because correlation does not necessary implies causality. The conclusion is correct since the correlation is significant. The conclusion is incorrect; Instead we should conclude that annual personal income increases more years of education.
