I give medalsss! I need help with just one more question. If both of these 5th placers from 2008 (Man A: 45.11, Woman B: 50.03) had competed in the 2013 semi finals (i uploaded the roster in the comments), where would they have placed, who would have done better? I think the answer is 11th and 7th, but that sounds too easy, here is the data. The previous question asked me to find the standard deviation of both, do i need this information or is it irrelevant?

Look on the men's chart for values near 45.11 we have Kevin Borlee in 9th place at 45.03 then Chris Brown in 10th place at 45.18 man A at 45.11 is in the middle of the two. So man A will take over 10th place and push Chris Brown to 11th place since man A is faster by 0.07 seconds. The runners from Chris Brown on down will all be pushed down a rank to fit in man A.

jimthompson5910 (jim_thompson5910):

you will do the same for the women as well

OpenStudy (x3_drummerchick):

thats what i figured, but i just thought that seemed too easy, i thought they would want more of a complex answer in relation to the standard deviation that i had calculated prior

jimthompson5910 (jim_thompson5910):

btw, the answers are 10th for man A and 7th for woman B so you had the woman B correct

OpenStudy (x3_drummerchick):

i mistyped man A :( but yeah it made sense to put the information into the data like that, it just seemed too easy, i thought they would want something more complex, ya know?

jimthompson5910 (jim_thompson5910):

so they had you calculate standard deviation, but you've yet to use it?

OpenStudy (x3_drummerchick):

yes

jimthompson5910 (jim_thompson5910):

hmm maybe they'll ask about estimating the range based on the std dev

OpenStudy (x3_drummerchick):

they asked for the range, median, mode and standard deviation in the first question, then they asked this one

I gotcha
