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.
