Problem 3 - Download the file "Data_100.csv" attached. Using the data in the file, create a box plot. Also create a histogram by using the fact that the number of datapoints within a range is a good representation of the probability the distribution would be within that range. For example, if there are 7 datapoints between 0 and 5, P(0 ≤ X ≤ 5) ∼= 0.07. Divide the whole range into 10 disjoint adjacent equi-width intervals.
