Question

Of the many species of oak trees in the United States, 28 grow on the Atlantic Coast and 11 grow in California. The back-to-back stemplot displays data on the average volume of acorns (in cubic centimeters) for these 39 oak species. Which of the following are correct comparisons of the distributions of acorn volumes for the Atlantic Coast and California?

Answer 1

The distribution of acorn volumes is slightly higher for oak species on the Atlantic Coast compared to oak species in California.

Step-by-step explanation:

The stemplot displays data on the average volume of acorns for oak species on the Atlantic Coast and in California. From the stemplot, we can compare the distributions of acorn volumes for the two regions:

• For oak species on the Atlantic Coast, the acorn volumes range from about 62 to 72 cubic centimeters.
• For oak species in California, the acorn volumes range from about 64 to 68 cubic centimeters.

Based on this comparison, we can see that the distribution of acorn volumes is slightly higher for oak species on the Atlantic Coast compared to oak species in California.
