This table shows the results in inches.City A 63 60 70 66 70 73 78 73 69 75City B 67 73 75 73 69 78 76 74 72 74Which conclusions can you draw about the heights of the players from the two cities?Select each correct answer.On average, the players in City A are a few inches taller than the players in City B.On average, the players in City A are a few inches shorter than the players in City B.On average, the players in the two cities are about the same height.The heights of the players in City A are more variable than the heights of the players in City B.The heights of the players in City A are less variable than the heights of the players in City B.The heights of the players in the two cities vary by about the same amount.
Question
Answer:
to find average add the heights and divide by number, do this for both cities:city A:
63 + 60 + 70 + 66 + 70 + 73 +78 + 73 + 69 + 75 = 697
697 / 10 = 69.7
shortest is 60, tallest is 78, difference = 78 -60 = 18
city b :
67+73+75+73+69+78+76+74+72+74 = 731
731 / 10 = 73.1
shortest is 67, tallest is 78, difference = 78-67 = 11
answers:
On average, the players in City A are a few inches shorter than the players in City B.
