A completely randomized design is an appropriate design to use in this situation because There is no blocking variable, and incentive plans will be randomly assigned to the workers.

A completely randomized design (CRD) is the simplest design for comparative experiments because it employs only two basic experimental design principles: randomization and replication.

By randomization, we mean that the experimental units' run sequence is determined at random.

Treatments are assigned to experimental units or plots in a completely random manner in CRDs. CRD can be used for either single-factor or multifactor experiments.

According to the question,

The quality control manager of a large factory wants to find out the number of defective items . For that 10 workers are selected Randomly and these worker will work on item according 3 incentive plans Means Replication is 3.

What is null hypothesis?

A null hypothesis is an educated guess or a prediction of the expected outcome of a particular experiment. It is a statement that assumes there is no difference between two groups or no association between two variables. The null hypothesis is often the opposite of the alternative hypothesis, which is the prediction that the researcher is hoping to prove.

Example 1: In a study of the effectiveness of a new drug for treating depression, the null hypothesis would be that the drug has no effect on depression levels.

Example 2: In a study of the association between smoking and lung cancer, the null hypothesis would be that there is no association between the two variables.

Example 3: In a study of the effect of a new educational program on student performance, the null hypothesis would be that the program has no effect on student performance.

Drink: $5

Candy : $3.75

Step-by-step explanation:

Let d = the cost of a drink

Let c = the cost of a candy

9d + 4c = 60

10d + 2c = 57.50 ⇒ Mult. by -2 ⇒ -20d -4c = -115  Add this to the first equation

-20d  - 4c = -115

9d + 4c = 60

-11d = -55  Divide both sides by -11

d = 5

A drink costs $5.00.

Plug in 5 for d in either of the two equations to solve for c

9d + 4c = 60

9(5) + 4x = 60

45 + 4c = 60  Subtract 45 from both sides

4c = 15  Divide both sides by 4

x = 3.75

Answer/Step-by-step explanation:

Since the axes are labelled and there are nice points marked on the line, you can practically SEE the slope here without any calculating, just by counting. Start with a point and find the directions to the next point. To get from one point to the next, go UP2 and OVER3.

"UP2 and OVER3" is the slope 2/3.  Double check that you get a slope that is positive because the line is going up to the right, it should have positive slope.

If the teacher is insisting that you use the slope formula, then name two of the points, such as (0, 4) and (3, 6). First subtract the y's, 6 - 4 is 2, put that on top of a fraction. Then subtract the x's, 3 - 0 is 3, put that on the bottom of a fraction. You get 2/3 again. Doesn't matter what points you use, since they are all on the same line it will come out the same.

E(max(X, Y )) = PxPy max(x, y)p(x, y)

MGFs means moment generating function. Every distribution function has a unique mgf

Make X a random number. We say that X has a moment generating function, and the function

Mₓ(t) = E(e^tx)   is referred to as the moment generating function of X

However, not all random variables have a moment generating function. However, every random variable has a unique function—an additional transform with properties comparable to those of the mgf.

The second creating capability (mgf) is a capability frequently used to describe the circulation of an irregular variable.

The moment-generating function is extremely useful for the following reasons:

1. Moments can be easily calculated with it; At zero, its derivatives are equivalent to the random variable's moments;

2. The mgf of a probability distribution is what makes it unique.

Answer:

C)  Domain:  all real numbers x except x = ±2

E)  f(x) → ∞ as x → -2⁻ and as x → 2⁺, f(x) → -∞ as x → -2⁺ and as x → 2⁻

Step-by-step explanation:

Given function:

[tex]f(x)=\dfrac{3x^2}{x^2-4}[/tex]

The domain of a function is the set of all possible input values (x-values).

A rational function is undefined when the denominator is equal to zero.

The denominator of the given function is zero when:

[tex]\implies x^2-4=0[/tex]

[tex]\implies x^2=4[/tex]

[tex]\implies \sqrt{x^2}=\sqrt{4}[/tex]

[tex]\implies x= \pm 2[/tex]

Therefore the domain of the function is:

The excluded x-values are x = -2 and x = 2.

To find the behaviour of the function near the excluded x-values, input values of x that are very near either side of excluded values:

[tex]x \rightarrow -2^-: \quad f(-2.001)=\dfrac{3(-2.001)^2}{(-2.001)^2-4}=3002.250...[/tex]

[tex]x \rightarrow -2^+: \quad f(-1.999)=\dfrac{3(-1.999)^2}{(-1.999)^2-4}=-2997,750...[/tex]

[tex]x \rightarrow 2^-: \quad f(1.999)=\dfrac{3(1.999)^2}{(1.999)^2-4}=-2997.750...[/tex]

[tex]x \rightarrow -2^+: \quad f(2.001)=\dfrac{3(2.001)^2}{(2.001)^2-4}=3002.250...[/tex]

Therefore, the behaviour of the function near the excluded x-values:

Step-by-step explanation:

None of the options are valid because the specified functions are both parabolic.

Functions represent the connection between two groups of values. For instance, if y=f(x), each value of x has a corresponding value in the set of y. The dependent variable is Y, and the independent variable is x.

An example of a rule is a function, which produces one output for a single input. Alex Federspiel is the picture's author. Y=X2 is an illustration of this. You only get one output for y if you enter anything for x. The fact that x is the input value leads us to say that y is a function of x. In mathematics and the sciences, functions are fundamental for constructing physical relationships.

Given functions in this case are

The midpoint rule, also known as the rectangle method or mid-ordinate rule, is used to estimate the area under a simple curve.

The number of sheep originally on the farm will be equal to 200.

The Latin phrase "per centum," which means "by the hundred," is where the English word "percentage" comes from.

Percentage segments are those with a numerator of 100. In other words, it is a connection where the whole is always deemed to be valued 100.

As per the given information in the question,

Let the number of animals originally at the farm is x.

60% of the animals are cows.

So, 0.6x are cows.

If there are 60% cows, then there are 40% of sheep.

So, 0.4x are sheep.

The quantity of sheep multiplies when many cows and sheep were introduced to the property.

As a result, the farm now has the same amount of sheep that it did before.

Number of sheep added = 0.4x

There are total 260 animals added to the farm.

So,

Number of sheep added = 260-0.4x

Total number of animals = x + 260

The percentage of cows increased to 20%.

Initial number of cows at farm + cows added = Initial number of cows at farm + 20% of the total cows initially at the farm.

0.6x + (260-0.4x) = 0.6x + 0.2(0.6x)

0.6x+260-0.4x = 0.6x+0.12x

0.2x+260 = 0.6x+0.12x

0.2x+260 = 0.72x

260 = 0.52x

x = 260/0.52

x = 500

Thus, the farm's initial animal population was 500.

0.6x = the amount of cows that were first on the farm= 0.6(500) = 300 cows

0.4x = the amount of sheep that were initially on the farm = 0.4(500) = 200 sheep
