In a gymnasium, the weights of all people come to exercise will be recorded. One day the weights of 10 people were recorded as 58 kg, 70 kg, 59.5 kg, 62 kg, 66.4 kg, 72 kg, 81.3 kg, 75 kg, 83.3 kg and 75.5 kg. How many of them weigh more than the average weight? a) 4 b)5 c) 6 d) 7

Answer 1

B.

Explanation:

Average =
`(58 + 70+59.5+62+66.4+72+81.3+75+83.3+75.5)/(10) =(703)/(10) =70.3`

Now find how many are greater than 70.3

72, 81.3, 75, 83.3, and 75.5
