Question: Please find below attached scatterplot between A and B. If the outlier (x=20, y=5) is removed, how will the statistical significance of a hypothesis test

  1. Please find below attached scatterplot between A and B. If the outlier (x=20, y=5) is removed, how will the statistical significance of a hypothesis test of b1 change? What about the sample t-statistic and p-value for the previous hypothesis test change? Increase/ decrease/ no change?
  2. Please look at the regression output. Is there any way that I can calculate the Standard Error of test$x?
