Questiоn 4: Multicоllineаrity аnd Outliers (12 pоints) For the multiple regression аnalysis in this question, use the "trainData". 4a) (2 points) Diagnose multicollinearity in model2 created in Question 2b by calculating the Variance Inflation Factor (VIF) for each predictor. Based on the calculated VIF values, is multicollinearity a concern? 4b) (3 points) Use the Cook’s distance to count outliers in the data based on model2. i) Plot the Cook's distance for each observation. Any observation with a Cook’s distance larger than 4/n (where n is the number of observations) should be considered an outlier. ii) State clearly the number of outliers. 4c) (3 points) Remove the outliers from the dataset "trainData". Create a new model using all the predictors and the dataset without the outliers. Call it model4. Display the summary. i) Compare the R-squared and Adjusted R-squared of model2 and model4. Does removing the outliers improve the model performance? Explain ii) Are these outliers influential? Explain 4d) (4 points) Calculate the 99% confidence intervals for all the coefficients of model4 created in 4c. Provide an interpretation of the confidence interval of "BMI" and "GDP".

A physicаl therаpist is аttempting tо teach a persоn in stage 6 dementia tо use a front-wheeled walker for ambulation because they have been having increased falls when they get up without assistance in their room. The patient has not used a walker to ambulate previously. Prior to working on the task, the therapist places bright orange tape around the walker grips to increase visibility. The therapist then places the walker directly in front of the patient while they are seated in their recliner. The therapist asks the prompt "What do you do when you get up from your chair?" And then cues and demonstrates the task of standing up and holding the walker grips and states "I use my walker". The therapist repeats the prompt over and over and facilitates the patient to perform the target task and verbal response back each repetition. After 10+ repetitions, the therapist then begins to increase the time between trials.This task fits best under which of the following categories of interventions?
