  5. Are the distributions of thicknesses skewed, or approximately symmetric?
  6. Delete outliers as appropriate, and compute the mean thickness for new and for recycled wafers.
  7. Delete outliers as appropriate, and compute the median thickness for new and for recycled wafers.
  8. Delete outliers as appropriate, and compute the standard deviation of the thicknesses for new and for recycled wafers.
