Homework 6 Coding Hidden Tests

Q2a¶

Your train_rmse_cpc should be should be close to 1.311759 Your test_rmse_cpc should be close to 2.143703

Q3a¶

The following code should return True

np.random.seed(100)
_peer_assessments_0 = bootstrap_sample(cleaned_college_data, 1)[0]["Peer Assessment Score (1-5)"]
_six_yr_grad_rate_2 = bootstrap_sample(cleaned_college_data, 1)[0]["Actual 6yr graduation rate"]
_test_3a_result = (
    np.isclose(_peer_assessments_0.mean(), 3.2508982035928145, atol = 8e-3) and
    np.isclose(_six_yr_grad_rate_2.std(), 11.846683695468434, atol = 8e-3)
)
bool(_test_3a_result)

Q3b¶
