Penny measured the time that it took her rat to run through a maze. she conducted the experiment 10 times and recorded the set of data below. times: 67 s, 69 s, 68 s, 66 s, 78 s, 70 s, 67 s, 69 s, 68 s, 66 s which time is most likely an outlier?

Below are the choices that can be found elsewhere:

a.66 s 
b.68 s 
c.70 s 
d.78 s

 An outlier is a result that is abnormally too high or too low. Most of the results fall between 66 and 70, but 78 seems to be abnormal, so it's your outlier.  The answer is D. Hope it helps :)

That is false even though water expands when frozen nothing changes at all
