The age values for the data tuples are (in increasing order) 13, 15, 16, 16, 19, 20, 20, 21, 22, 22, 25, 25, 25, 25, 30, 33, 33, 35, 35, 35, 35, 36, 40, 45,46, 52, 70. Show a boxplot of the data? Full explain this question and text typing work only We should answer our question within 2 hours takes more time then we will reduce Rating Dont ignore this lineQuestion 5: A random sample of 15 patients yielded the following data on the length of stay (in days) in the hospital. 5, 6, 9, 10, 15, 10, 14, 12, 10, 13, 13, 9, 8, 10, 12. Find the mean, median and modeWhich one of the following statistics is resistant to outliers? (A) mean B) range Q1 D standard deviation
- Please explain clearly why the 3rd answer is correct. thank youPlease help with an explanation. All running times refer to the worst-case analysis.Plot following curves in the SAME figure where x-axis is "Model Complexity" and y-axis is the value: (1) Bias; (2) Variance; (3) Training Accuracy; (4) Testing Accuracy; [Paste your plot here]
- Do you need to normalize median age when making your choropleth map? Why or Why not?First, perform the following tasks: • Make a linear regression model with all the features in the dataset. Use train_test_split to keep 20% of the data for testing. • Use your model to predict values for test set and print the predictions for the first 10 instances of the test data and compare them with actual values. • Print the coefficient values and their corresponding feature name (e.g. age 43, bmi 200, .) • Note that you can access feature_names from diabetes dataset directly • Calculate training-MSE, testing-MSE, and R-squared value. Compare the two models. Did using all available features improve the performance? In [ ]: # Your code goes here In [ ]: # Your code goes hereOne hundred students were asked whether they had taken courses in any of the three subjects, Mathematics, Computer Science and Information Technology. The results were given below. 45 had taken Mathematics; 18 had taken Mathematics and Computer Science; 38 had taken Computer Science; 21 had taken Information Technology; 9 had taken Mathematics and Information Technology.; 4 had taken Computer Science and Information Technology and 23 had taken no courses in any of the subjects. Draw a Venn diagram that will show the results of the survey.
- Which Python module and method are used to create a multiple regression model for a given data set? Select one. linregress method from scipy module linregress method from statsmodel module ols method from scipy module ols method from statsmodel moduleModel evaluation Create a predictions variable using your fitted model and the test dataset; call it y_pred. Then get the accuracy score of your predictions and save it in a variable called accuracy. Finally get the confusion matrix for your predictions and save it in a variable called confusion_mat. Code: y_pred = Noneaccuracy = Noneconfusion_mat = NoneWhich of the following correctly represents the coefficient of determination in terms of the variance that is an output from the analysis of variance table?
