Multiple linear regression would be the best choice as it allows for the examination of the relationship between the number of sales and both the number of years with the company and the scores on the business aptitude test, while controlling for the potential effects of other variables. One-way ANOVA would only allow for the examination of the relationship between the number of sales and one variable (years with the company or aptitude test scores) at a time, while two-way ANOVA would allow for the examination of the relationship between the number of sales and both variables but would not control for the potential effects of other variables. Simple linear regression would only allow for the examination of the relationship between the number of sales and one variable (either years with the company or aptitude test scores) at a time.
