Step 1: Question (a) Which of carat weight, cut, color or clarity best distinguishes between diamonds with a price of less than $5,000 and those with a price of $5,000 or greater? To answer this, we need to look at the distribution of the different attributes in relation to the price. Price Distribution: From the first histogram (Price), we see a clear distinction in the number of diamonds priced below $5,000 and those priced above $5,000. Clarity: The histogram shows varying counts across clarity categories, but does not provide a clear split around the $5,000 mark. Cut: The distribution of cuts (Good, Very Good, Excellent, Ideal) is fairly even without a distinct split around the $5,000 mark. Color: The color distribution does not show a clear pattern that would distinguish diamonds around the $5,000 mark. Carat Weight: The carat weight histogram shows that diamonds with higher carat weights are priced higher. This is the attribute that shows a clear distinction between diamonds priced below $5,000 and those above. Answer for (a): Carat weight Question (b) Which of the following statements best characterizes the diamonds with a price that is less than $3,000? Small diamonds with weights less than 1 carat: The carat weight histogram shows a significant number of diamonds under 1 carat in the lower price ranges, supporting this statement. Diamonds classified as VS1 or VS2 for clarity: The clarity histogram shows that there is a significant number of SI1 and VS2 diamonds, but not necessarily a clear majority under $3,000. Diamonds classified as F, E, or D for color: The color histogram shows a spread of diamond colors, but there is no clear indication that the majority of diamonds under $3,000 fall within F, E, or D. Diamonds classified as Good or Very Good for cut: The cut histogram shows a significant number of diamonds in the Good and Very Good categories. However, to make a strong characterization, more context on the price distribution would be necessary. Answer for (b): They are small diamonds with weights less than 1 carat. Explanation: These answers are based on visual inspection of the provided histograms. Step 2: Question (c) What is the clarity of the highest priced diamond? To determine this, we need to look at the distribution of clarity in relation to the highest priced diamonds. The highest priced diamonds are most likely to be those with the highest clarity, as clarity significantly impacts the price of diamonds. From the clarity histogram, it can be inferred that diamonds classified as IF (Internally Flawless) typically fetch the highest prices due to their superior clarity. Answer for (c): IF Question (d) What do the two highest priced diamonds have in common? To determine this, we need to consider the factors that significantly affect the price of diamonds: Clarity Classification: Higher clarity often leads to higher prices, but two diamonds with the highest price may not necessarily have the same clarity classification. Cut Classification: Cut also significantly impacts the price, with Excellent or Ideal cuts being the most valuable. Carat Weight: Higher carat weight generally corresponds to higher prices. It is very likely that the two highest priced diamonds fall within the same carat weight range. Color Classification: While color does impact the price, it is less likely that both highest priced diamonds share the exact same color classification compared to carat weight. Given these points, it is most probable that the two highest priced diamonds share the same carat weight range. Answer for (d): They are in the same carat weight range. Question (e) There is one diamond that was classified as an outlier in terms of carat weight. Which of the following describes this diamond? To answer this, we need to identify the outlier in the carat weight histogram. The outlier will typically have a carat weight significantly higher than the rest. The cut of this diamond is rated as ideal. The outlier is not necessarily related to the cut. The color of this diamond is rated as K. The color histogram shows no distinct pattern indicating an outlier related to color. It is the diamond in the data set with the highest price. The highest carat weight diamond is often the most expensive, making this a likely choice. The clarity of this diamond is rated as VS2. The clarity histogram does not show any specific outlier information. None of the above. Only choose this if none of the options make sense. Answer for (e): It is the diamond in the data set with the highest price. Question (f) There are two diamonds that are classified as Ideal for cut. Which of the following describes the diamond with the smaller carat weight? It is the diamond in the data set with the lowest price. A smaller carat weight often correlates with a lower price, but other factors like clarity and color also play a role. The color of this diamond is rated as F. This statement requires verification from the color histogram. The clarity
