Suppose Y is numeric variables and X is an indicator variable. Consider the following fitted line y = 55 + 3X.
Which statement is correct?
a. The fits results in two non-parallel lines with different y-intercepts, one having a 55 y-intercept and the other having a 58 y-intercept.
b. The fit results in two identical lines, each with slope 3 and y-intercept being 55.
c. The fit results in two identical lines, each with slope 3 and y-intercept being 58.
d. The fit results in two parallel lines each with slope 3.
e. The fit results in two horizontal lines, one at Y = 55 and one at Y = 58.
