👋 Hi, how can I help?
Score: Week 3 ANOVA and Paired T-test                                                                                        
  At this point we know the following about male and female salaries.                                                                                      
  a. Male and female overall average salaries are not equal in the population.                                                                                  
  b. Male and female overall average compas are equal in the population, but males are a bit more spread out.                                                                          
  c. The male and female salary range are almost the same, as is their age and service.                                                                                
  d.  Average performance ratings per gender are equal.                                                                                    
  Let’s look at some other factors that might influence pay – education(degree) and performance ratings.                                                                                
<1 point> 1 Last week, we found that average performance ratings do not differ between males and females in the population.                                                                          
    Now we need to see if they differ among the grades. Is the average performace rating the same for all grades?                                                                          
    (Assume variances are equal across the grades for this ANOVA.)   You can use these columns to place grade Perf Ratings if desired.
