Answer:
6 bench seats creates an arc of 56.52 foot.
Step-by-step explanation:
We are given the following in the question:
Total number of bench seats in Ferris wheel = 24
Radius of Ferris wheel = 36 feet
We have to find the arc length created by 6 bench seats.
Angle formed by 6 bench seats =
![\theta = \dfrac{6}{24}\times 360 = 90^\circ](https://tex.z-dn.net/?f=%5Ctheta%20%3D%20%5Cdfrac%7B6%7D%7B24%7D%5Ctimes%20360%20%3D%2090%5E%5Ccirc)
Arc length =
![\dfrac{\theta}{360}\times 2\pi r](https://tex.z-dn.net/?f=%5Cdfrac%7B%5Ctheta%7D%7B360%7D%5Ctimes%202%5Cpi%20r)
Putting values, we get,
![\dfrac{90}{360}\times 2(3.14)(36) = 56.52\text{ feet}](https://tex.z-dn.net/?f=%5Cdfrac%7B90%7D%7B360%7D%5Ctimes%202%283.14%29%2836%29%20%3D%2056.52%5Ctext%7B%20feet%7D)
Thus, 6 bench seats creates an arc of 56.52 foot.
Answer:
Step-by-step explanation:
Hello!
Suppose that the objective of the experiment is to test if a certain treatment modifies the mean of the population of interest.
If for example, the treatment is "new fertilizer" and the population of interest is "yield of wheat crops"
Then you'd expect that using the new fertilizer will at least modify the average yield of the wheat crops.
The hypotheses will be then
H₀: μ = μ₀
H₁: μ ≠ μ₀
Where μ₀ represents the known average yield of wheat crops. (is a value, for this exercise purpose there is no need to know it)
We know that the treatment modifies the population mean, i.e. the null hypothesis is false.
The sample we took to test whether or nor the new fertilizer works conducts us to believe, it does not affect, in other words, we fail to reject the null hypothesis.
Then we are in a situation where we failed to reject a false null hypothesis, this situation is known as <em><u>Type II error</u></em>.
I hope this helps!
