The only difference between speed and velocity is that velocity also includes direction, so if the speed is the same but the velocity is changing, that means that the direction is changing on the ride, but the speed is staying the same.

Answer:
Step-by-step explanation:
The null hypothesis is
H0: μ = 32.6
The alternative hypothesis is
Ha: μ ≠ 32.6
The calculated test statistic is 2.66 for the right tail and - 2.66 for the left tail
Since the critical values for both tails is ± 2.145, we would compare the critical values with the test statistic values
In order to reject the null hypothesis, the test statistic must be smaller than - 2.145 or greater than 2.145
Since - 2.66 < - 2.145 and 2.66 > 2.145, we would reject the null hypothesis.
Therefore, Reject H0. There is sufficient evidence to support the claim that the mean is different from 32.6.
2) Test statistic: t = 2.66. Critical values: t = ±1.96
Since - 2.66 < - 1.96 and 2.66 > 1.96, we would reject the null hypothesis. Then
Reject H0. There is sufficient evidence to support the claim that the mean is different from 32.6.
The correct answer is D, since a rotation of 360 has no effect, since the figure does a whole turn and returns where it was.
