input: Write a python function to calculate the mean, median, and mode of a given list using numpy.
  assert calculate_statistics([38, 45, 42, 43, 37, 41, 53, 90, 55, 72, 85, 56, 68, 54, 43, 42, 39, 70, 62, 68]) == (53.65, 53.5, 42)
  assert calculate_statistics([1, 2, 3, 4, 5]) == (3.0, 3.0, 1)
  assert calculate_statistics([10, 20, 20, 30, 30, 30]) == (23.333333333333332, 25.0, 30)
output: import numpy as np

      mean = np.mean(data)
      median = np.median(data)
      mode = stats.mode(data)[0][0]
