When comparing two populations with the same variable of interest in the same unit of measure, the larger the standard deviation, the dispersion there is in the distribution?

greater. Standard deviation is a measure of how much variability there is in a data set. A higher standard deviation means more variability, and therefore the data is more dispersed. A data set with a high standard deviation will have a wider range of values compared to the average, while a data set with a low standard deviation will cluster more closely about the average.

At a constant it will take one hour to travel 32 mi.at that speed it will take 1/2 hr to travel the remaining 16 mi.it will take 1+1/2 hr to travel the 48mi @ 32mph.so 1 hr = 60 min& 1/2 hr = 30 min1+1/2 hr = 90 min.there are 60s in each 90 × 60 = 3600 seconds.the real question seriously is he why are they driving so slow? ! lol.
