If the variance of the data values in a population is 196, what is the standard deviation of the data values?

The standard deviation is the square root of the variance

so if the variance is 196, then the standard deviation is the sqrt of 196, which is 14

221,500 is the answer

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.
