Use a simple linear regression to estimate the relationship between workers' earnings (Y) and gender (X) (Model A). You may use the Data Analysis Tool Pack. Based on the Excel regression output, first write down the estimated regression equation and interpret the slope coefficient. Carry out any relevant two-tailed hypothesis test of the slope coefficient using the critical value approach, at the 5% significance level, showing the step by step workings/diagram in your report. Interpret your hypothesis test results.

Just asking how am i able to do this as my x variable in the linear regression is just one number. As gender is either male or female.
