Hey @MAYANK4,
Your notebook gives an error while compiling.

---------------------------------------------------------------------------
TypeError                                 Traceback (most recent call last)
Cell In[18], line 4
      1 # Test your code
      3 alpha = 0.05
----> 4 reject_nh = reject_nh_t_statistic(t, dof, alpha)
      6 print(f"The null hypothesis can be rejected at the {alpha} level of significance: {reject_nh}\n")
      8 msg = "" if reject_nh else " not"

Cell In[17], line 17, in reject_nh_t_statistic(t_statistic, dof, alpha)
     15 reject = False
     16 ### START CODE HERE ###
---> 17 p_value = 2 * (1 - t.cdf(np.abs(t_statistic), dof))
     19 if p_value  < alpha:
     20     reject = True

TypeError: bad operand type for abs(): 't_gen'

Why are you trying to submit such a notebook before resolving the error? Please resolve all the errors first, and then submit your notebook.

Hint: Try to look up the documentation for np.abs.

Cheers,
Elemento

Thanks… It was just a small mistake. I went through the documentation and coded it down. :sparkles:
