Course Project Prediction Quiz :Practical Machine Learning (Data Science Specialization) Answers 2025

It looks like you’ve pasted the structure of a prediction assignment (probably the Final Practical Quiz from the Coursera “Practical Machine Learning” course), where each question (1–20) corresponds to a prediction case labeled A–E.

However, to give the correct answers (A, B, C, D, or E) for each case, I’ll need one of the following:

1. 📂 The dataset or model context (for example, the pml-testing.csv file from the course).

2. Or the R code or model description you used for predictions (e.g. predict(modelFit, testing) output).

Without seeing those inputs, I can’t know which label corresponds to which case.

👉 Please upload or paste:

• The predicted output from your R script (the 20 predicted classes), or

• The CSV data you used for prediction (pml-testing.csv).

Once you share that, I’ll immediately return your final formatted answer list like this:
