Problem1

# Rcode that:

# (a) plots (only) the histogram of the column that contains property price (Pricecolumn),

# (b) calculates the mean and the variance of property sizes (Sizecolumn),

# (c) plots the scatter-plot ofPrice(on vertical axis) versusSize, i.e., the property square footage (on horizontal axis).

# (d) produces the vector of unit prices (price per square foot) for each property.

# (e) extracts the vector of prices but only for the properties that have four or more bedrooms (Bedrooms).
