There are three financial aid counselors. If a student’s last initial is from A – H, let them know that their counselor is Jon Stewart. If a student’s last initial is from I – Q, let them know that their counselor is Chelsea Handler. If a student’s last initial is from R – Z, let them know that their counselor is Brian Williams.Ask student for the FICO score, if it’s less than 660 tell that this student cannot have a loan.

Exercise 12: Suppose we would like to use scikit-learn to solve a multiple linear regression problem using ₁ regularization. Which of the following is a possible option to use? A) "sklearn.linear_model.Logistic Regression" class with default choices of param- eters B) "sklearn.linear_model.Logistic Regression" class by changing the default choice of "penalty" and "solver" parameters to "11" and "liblinear", respectively. C) "sklearn.linear_model.Lasso" class with default choices of parameters D) "sklearn.linear_model. Ridge" class with default choices of parameters

Match the metrics with their corresponding definition. TPR/Recall PPV/Precision TNR/Specificity Accuracy [Choose ] The ratio of correctly classified predictions over all predictions The ratio of the positive predictions that were correct over the total number of positive predictions made. The ratio over the number of negative predictions that were correct over all the true negative class samples. The ratio over the number of positive predictions that were correct over all the true positive class samples [Choose ]

Step 4: Hypothesis Test for the Population Mean (II) A team averaging 110 points is likely to do very well during the regular season. The coach of your team has hypothesized that your team scored at an average of less than 110 points in the years 2013-2015. Test this claim at a 1% level of significance. For this test, assume that the population standard deviation for relative skill level is unknown. You are to write this code block yourself. Use Step 3 to help you write this code block. Here is some information that will help you write this code block. Reach out to your instructor if you need help. 1. The dataframe for your team is called your_team_df. 2. The variable 'pts' represents the points scored by your team. 3. Calculate and print the mean points scored by your team during the years you picked. 4. Identify the mean score under the null hypothesis. You only have to identify this value and do not have to print it. (Hint: this is given in the problem statement) Assuming the…
