Which would be the best measures of center and variation to use to compare the data? The scores of Group B are skewed right, so the mean and range are the best measures for comparison. Both distributions are nearly symmetric, so the mean and the standard deviation are the best measures for comparison. Both distributions are nearly symmetric, so the median and the interquartile range are the best measures for comparison. The scores of both groups are skewed, so the median and standard deviation are the best measures for comparison.

Ответ:
The answer would be
B. Both distributions are nearly symmetric, so the mean and the standard deviation are the best measures for comparison.
Step-by-step explanation:
I took the test and got it right ;)
Ответ:
the solution is (-0.05,-1.6) see the attached figure
proceed to check it
f(x)=−32x
g(x)=(12)x−1
f(x)=g(x)-------------- >-32x=12x-1----------- > 20x=-1---------> x=1/20=-0.05
f(x)=32*(-1/20)=-32/20=-8/5=-1.6
the solution is the point (-0.05,-1.6) (see the attached figure)
