An experimenter records the results of a large sample survey on a histogram. outcomes that lie far outside standard deviations of the data are

a: medians
b: statistically significant
c: mean

Therefore, those outcomes that lie outside the standard deviations of the data would be considered as statistically significant. The answer to this is option B.

She should use 12/3 to measure

12+3b -1=-5-b -12-1+5=-b-3b -8=-4b
