Question

Suppose the following table was generated from sample data of 2020 employees relating hourly wage to years of experience and whether or not they have a college degree. Using statistical software, create an indicator (dummy) variable for the variable "Degree" and find the regression equation. Is there enough evidence to support the claim that on average employees with a college degree have higher hourly wages than those without a college degree at the 0.050.05 level of significance? If yes, write the coefficient of the dummy variable in the space provided, rounded to two decimal places. Else, select "There is not enough evidence."
