1.4 [1 pt] We pretended that the distribution of tip percentages in the population is the same as the distribution of tip percentages in our sample. Let's check (i) that our sample_mean is close to the mean of our variable random_sample_means, and (i) that our standard_error is close to the standard deviation of our variable random_sample_means. Store the differences in the variables called diff_means and diff_std. In[12]: Student's answer (Top) diff_means = None diff_std = None # YOUR CODE HERE
