А Daniel by 3 feet
B Hector by 3 feet
С Daniel by 6 feet
D Hector by 6 feet

Answer 1

Answer:

Option B : Hector by 3 feet is the correct answer.

Step-by-step explanation:

Given that:

Mean of Daniel = $\frac{Sum\ of\ quantities}{Number\ of\ quantities}$

Mean of Daniel = $\frac{27+30+34+35+34}{5} = \frac{160}{5}$

Mean of Daniel = 32 feet

Mean of Hector = $\frac{38+24+38+40+35}{5} = \frac{175}{5}$

Mean of Hector = 35 feet

Therefore,

Hector has a greater mean

Difference = Hector's Mean - Daniel's Mean

Difference = 35 - 32

Difference = 3 feet

Hence,

Option B : Hector by 3 feet is the correct answer.
