Answer
Here n = 39, x̅ = 0.46, s = 6.87, df = 38
$s_{x̅} = \frac{0.46}{\sqrt 39} = 1.10$
$t = \frac{0.46 - 0}{1.10} = 0.418$
Using tech, we have P = 0.339
Since P > 0.05, we fail to reject Null Hypothesis. Hence, we do not have sufficient evidence that the football filled with Helium travels farther than the air-filled football.
