Refer to the Real Estate Data—Saskatoon online, which reports information on list prices, type, number of full and half bathrooms, number of bedrooms, and total square feet. Sort the data into a table by list price (class widths of $500 000) and the square footage (class widths of 1000). Compute the following probabilities:
1. The dwelling has more than 1000 square feet.
2. The dwelling is listed for less than $500 000 and is from 1000 to under 2000 square feet.
3. Given that the dwelling is listed for less than $500 000 and is from 1000 to under 2000 square feet.
4. The dwelling is under 1000 square feet or is listed for less than $500 000.
