Some track and field athletes feel that they are more likely to win a race if they start on the inside lane. The data above show
ivolga24 [154]

Answer:

D.]

Step-by-step explanation:

We will find the standard deviation and variance:

Variance= Ex^{2}-[[E(x)]^{2}

 E[x] = 3.462

E[{x}^2]= 31.86

Var(x)= 31.86-(3.462)^2 = 28.4

Standard deviation = \sqrt{Var(x)}

                               = \sqrt{28.4}

                               = 5.833 = 6(aproximately)

Therefore, the chances of winning are equal in each lane.
