    P-value of intercept = 0 meaning? Can age be independent var in simple regression?

    Would it be correct to just leave the outlier in but I just write something like "Hey! thats an outlier, an interesting find , hopefully future analysis could be done with bigger sample size to find out more" ? Edit: or would it be better to remove outliers and re run?

    P-value of intercept = 0 meaning? Can age be independent var in simple regression?

    Thank you for the reply. Such a residual plot is fine right for a simple linear regression?

    P-value of intercept = 0 meaning? Can age be independent var in simple regression?

    Thank you! Does this mean my residual plot fulfills the assumption of linearity as well? I am also quite worried about the outlier ( 25 yrs old car) , should it have been removed or kept ? I read online that outliers should not be removed unless its a clear error.

    P-value of intercept = 0 meaning? Can age be independent var in simple regression?

    Hi I recently got into statistics... I am not too sure if this is the correct place to ask, I have included pictures as well Can I test "age of used vehicle" as independent variable against "selling price" as dependent variable in a simple linear regression? Is my residual plot as shown weird...
