Considering the hypotheses tested, it is found that the p-value for Nicolas's test is of 0.101.
<h3>What are the hypotheses tested?</h3>
At the null hypotheses, it is tested if the mean is of 24, that is:
At the alternative hypotheses, it is tested if it is different, hence:
As we are testing if the mean is different of a value, we have a two-tailed test, with <em>t = -1.79 and 12 - 1 = 11 df</em>. Hence, using a t-distribution calculator, the p-value is of 0.101.

Answer:
Velocity = displacement / time
Distance = 3t^2 +2t +6 to find distance you need to plug in time = 2 sec
Distance = 3(2)^2 +2(2) +6
Distance = 3(4) +4 + 6
Distance = 12 + 4 +6
Distance = 22 meters
In this problem the displacement is the distance.
so
Velocity = 22 meters / 2 second
Velocity = 11 meters/second
