Study on New Drug Increasing White Blood Cell Count for Patients on Chemotherapy

Barterol is a drug designed to increase the white blood cell count for patients receiving chemotherapy. When subjects were tested with this drug, their white cell count reading (in thousands per ml) was recorded before and after the drug was taken. The results are shown in the following table. White blood cell counts are normally distributed within a population.

Subject      A       B       C       D       E        F       G       H        I        J        K       L

Is there sufficient evidence to support the claim that the drug is effective in increasing white blood cell counts? Use a significance level of 0.02. Show all steps of the hypothesis process.

Summary

The question belongs to Statistics and it is about testing a new drug that increases the number of white blood cells for patients receiving chemotherapy. The claim for the drug increasing white blood cells significantly has been given in the solution.
