Split the MR_X and MR_y into training set and test set. You should use the num training variable to extract the data from MR_X and MR_y. Extract the first 'num_training' samples as training data, and extract the rest as test data. Name them as: MR_train_X and MR_train_y for the training set MR_test_X and MR_test_y for the test set
1) Write the SQL code to add a column that shows the full name of the Employee in the Employee Table. The expecting format should be “Firstname Initial Lastname” (e.g., “John G News” for the EMP_NUM 101) 2) Write the SQL code to add a binary variable “Hire_prior_2000” in the Employee table. If the hire year (year of hire needs to be identified) is prior to 2000, then Hire_prior_2000=1, other wise Hire_prior_2000=0.

TODO 12 Let's now split our input data X and labels y into a train and test set using the train_test_split() function (docs). Here we'll use the 80-20 split rule where we use 80% of the data for training and 20% for testing. Lastly, we'll seed our split using the random_state keyword argument which will make sure we create the same split every time we run the function. Use the train_test_split() function to get a train and test split. Store the output into X_train, X_test, y_train, and y_test. Pass the required arguments X and y. Further specify we want to use 20% of the training data by setting the test_size keyword argument. Lastly, pass the keyword argument random_state=42 to set the random seed so we get the same split every time we run this code. Print the shape for X_train. Print the shape for y_train. Print the shape for X_test. Print the shape for y_test. # TODO 12.1X_train, X_test, y_train, y_test = todo_check([ (X_train.shape == (413, 29), 'X_train does not have the…
