Leverages

In statistics, the influence individual data points have on the regression coefficients in a linear regression model.

T-Statistic

A type of test statistic used in Student's t-test, calculated as the difference between an observed sample mean and a known population mean, divided by the standard error.

  • Examine and understand model diagnostics via residual plots and leverage point histograms.

Final Answer :
The points currently keep the slope value down.Omitting them should increase the value of the coefficient of English.The t-statistic should be greater than the current value.
