(a) All of the training times of which person had the greatest spread? Explain how you know.

(b) The middle 50% of the training times of which person had the least spread? Explain how you know.

(c) What do the answers to Parts 2(a) and 2(b) tell you about Adam’s and Miguel’s training times?

Answer 1

Answer: Yeah I’m completely stuck on this question I’m just gonna go with 61 because 10,211-10,115 is 61 miles and that’s the only realistic answer I can get. A) Miguel has a better spread because 105 – 88 = 17 Where as for Adam you have 106-91 = 15 which means Adam has a smaller spread than Miguel.

B) Yet again Adam has a smaller spread because his number is 15 compared to Miguel which is 17 its simple.

C) for this I would say Adam is consistent with his training because they’re all pretty much within 100 whereas Miguel is rather inconsistent with his training regimen they seem to range from 90 down to 80 .
