Task

In this exercise, your goal will be to determine the normality of the distribution using the Shapiro test. Along with visual analysis, this test allows you to verify that your distribution is indeed normal. This knowledge is key in controlled experiments.

  1. Read files.
  2. Do the Shapiro test of the Click column for the control sample.
  3. Do the Shapiro test of the Click column for the test sample.
