How many of the 15 recorded throw lengths were less than 90 percent of the longest recorded throw length?

Rationale

Nine of the 15 recorded throw lengths were less than 90 percent of the longest recorded throw length.

To determine how many throw lengths fall below 90 percent of the longest throw, we first identify the longest throw and then calculate 90 percent of that length. After analyzing the data, it is found that nine lengths do indeed meet this criterion.

A (Eight) YOUR ANSWER

Choosing eight would imply that only a few throws were significantly below the threshold. However, upon reviewing the data, this choice undercounts the total, as nine lengths are clearly below the 90 percent mark.

B (Nine) CORRECT

This is the correct answer as it accurately represents the count of throw lengths that are less than 90 percent of the longest throw. Each length was compared to the calculated 90 percent, confirming that precisely nine lengths fell short.

C (Ten) YOUR ANSWER

Selecting ten would suggest that an additional length, compared to the correct count, is below the threshold. However, a careful examination of the recorded lengths shows that only nine actually qualify, making this choice inaccurate.

D (Eleven) YOUR ANSWER

Opting for eleven indicates an overestimation of the lengths falling short of the threshold. The analysis reveals that only nine lengths are under 90 percent, thus this choice exceeds the actual count.

E (Twelve) YOUR ANSWER

Choosing twelve would imply that nearly all but three throws are below the threshold. This is inaccurate as the data shows that only nine lengths are less than 90 percent of the longest recorded throw, making this choice incorrect.

Conclusion

In summary, the accurate count of throw lengths falling below 90 percent of the longest recorded throw length is nine. This highlights the importance of precise data analysis in determining results, ensuring that conclusions reflect the true distribution of values within a dataset.

How many of the 15 recorded throw lengths were less than 90 percent of the longest recorded throw length?

Nine of the 15 recorded throw lengths were less than 90 percent of the longest recorded throw length.
