For the first helper function we have to use numpy.random.randn. The documentation notes that new code should use standard_normal and I tested it in the notebook. Grader doesn’t give me any errors.

This output “All tests passed” is with numpy.random.standard_normal instead of random.randn.

I also tried " numpy.random.Generator.standard_normal" But not all tests were passed. I will leave numpy.random.standard_normal unless a mentor tells me otherwise
