Focus on high performers

Performance ratings matter to organizations and individual employees. Being labeled a "high performer" can matter even more than the exact rating when the employee is considered for promotions, bonuses, and raises. Organizations can define "high performer" however they wish, and in this chapter, a high performer is any employee with a rating of 4 or 5 on the 5-point scale.

Create the new high_performer variable, and perform a statistical test on whether the women in this dataset are significantly less likely to be labeled high performers.
