title: st.ttest_ind in scipy returning a p-value of 0.0
body: <p>I am trying to conduct a hypothesis test but I am getting a p-value of 0. I can understand if it is really small but a 0.0 is leading me to believe that there is an error. Here is my code:</p>
  <pre><code>results = st.ttest_ind(
          ultimate_users['monthly_profit'], 
          surf_users['monthly_profit'], nan_policy = 'omit')
  
  print('p-value: ', results.pvalue)
  
  </code></pre>
  <p>output:
  p-value:  0.0</p>
