Question

three runners recorded their times for the 40 - yard dash over the period of a year. use the table to complete the statements. the fastest runner is, because she had the. the most consistent runner is, because she had the greatest interquartile range value greatest mean running time least interquartile range value least mean running time

runner	mean running time (s)	interquartile range (s)
lorena	7.4	0.2
zarena	6.9	0.8

Explanation:

Step1: Identify the fastest runner

The fastest runner has the least mean running - time. Comparing the mean running times: 6.2 (Alana), 7.4 (Lorena), 6.9 (Zarena). Since 6.2 is the least, Alana is the fastest.

Step2: Identify the most consistent runner

The most consistent runner has the least inter - quartile range. Comparing the inter - quartile ranges: 1.1 (Alana), 0.2 (Lorena), 0.8 (Zarena). Since 0.2 is the least, Lorena is the most consistent.

Answer:

The fastest runner is Alana, because she had the least mean running time.
The most consistent runner is Lorena, because she had the least interquartile range value.
