Using the data set from the sample of 513 patients from the Upper Volta HIV Registry assigned to you and R Commander:

1. Suppose you were to select one person at random from this data set. Use the Normal model to estimate the probability that this person has recorded more than 25 hours per week of moderate and vigorous physical activity (the variable 'MVPA'). Show any working or intermediary steps. (2 marks)

2. Discuss whether or not the Normal model was an appropriate probability model for addressing the previous question (part a). Use appropriate graphs and statistics to support your discussion. (3 marks)
