Determine by inspection which set has the greater standard deviation. Circle the set with the greater standard deviation and explain how you know. Set A: 60,62,65,68,70,71,74,75 Set B: 50,52,58,63,65,73,78,80 A box has 2 red chips, 2 blue chips, and 1 green chip. Two chips are randomly selected together. List the elements in the sample space. 5 chips total originally

Solution

The range for the first set is 75-60=15

The range for the second set is 80-50=30

Hence as range is also a measure of dispersion

So we can conclude that second group has greater standard deviation
