You are given test results for two drugs: A (results for the group of people getting drug A) and B (results for the other group of people getting drug B). 1) You need to assess whether there is a statistically significant difference in the effect in these patients. Use the null hypothesis, the inverse hypothesis, and Student's t-test for calculations. 2) construct a boxplot and histogram to visually confirm the result

import matplotlib.pyplot as plt
import numpy as np

def plot(A, B):
  plt.boxplot([A, B])
  plt.show()
  plt.hist([A, B])
  plt.show()
    
A = [1, 2, 3]
B = [4, 3, 2]
plot(A, B)
