Answer:

5 units (you are right!)

Step-by-step explanation:

The triangles ABD and BCD are similar.

Therefore,

VikaD [51]
This is basic alegbra, you set up a proportions equations with dozen of cookies over butter. 6/ 3/4 equals 3/x. You cross multiply, 6x equals 2 1/4. You divide 6 on both sides of the equation to isolate x, the variable. 2 1/4 divided by 6 equals 0.375. The answer is 0.375 cups of butter

Find the outlier of the set of data: 24, 37, 33, 31, 28, 25, 33, 12
natka813 [3]
Outlier - A value that "lies outside" than most of the other values.

The outlier is therefore 12, because it is not in the general range of values, which is on average around 29.

Even if a treatment has an effect, it is still possible to obtain a sample mean after the treatment that is very similar to the
vlada-n [284]

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!
