Answer:

847 students must be interviewed.

Explanation:

To reach this result we will use the following formula:

\(n = \frac{z^2*p*(1-p)}{e^2}\)

In this formula the letter "e" is equal to 0.04 (4%). Thus, we must find the values of "p" and "z", to find the "n", which refers to the confidence interval.

The question above did not show us what value should be used in "p". When we do not have information on this value, it is always recommended to use 0.5, which is the sample maximization value.

In the situation shown in the question above, a confidence interval of 98% is presented. Thus, it is implicit that we must adopt in "z" a value among the cumulative values of the z distribution of up to 1% or up to 99%. That way you can use any value between the range of 1% to 99%, you should look for that value in a table of Z, however, to facilitate the calculation we will use a value of the area of 99% in the distribution of z. This value is 2,327.

Now we can replace these values in the formula and find the value of "n".

\(n = \frac{2.327^2*0.5*(1-0.5)}{0.04^2} = 846.08\)

As there are no 0.8 students, we must round the number to 487. So we can say that it will be necessary to interview 847 students to create the confidence interval.

In order to find his cat in the dark, he would have to call out to his cat because a cat is a nocturnal animal that sees well at night.

Animals that exhibit nocturnality are those who are awake at night and asleep during the day. "Nocturnal" is a frequent adjective, whereas "diurnal" means the reverse. The senses of hearing, smell, and especially specialized eyesight are typically highly developed in nocturnal species.

Hence, it can be seen that it would be better to call out to the cat so he can locate him.

Approximately 97.06% of the world's population lives in countries other than Canada and Guam.

To find out what percentage of the world's population lives in countries other than Canada and Guam, we need to know the population of Canada, the population of Guam, and the total population of the world. We can then subtract the population of Canada and Guam from the total population of the world to find out how many people live in countries other than Canada and Guam.

Finally, we can divide this number by the total population of the world and multiply by 100 to find out what percentage of the world's population lives in countries other than Canada and Guam. Let's go through the steps. According to the World Bank, the population of Canada in 2021 is approximately 38 million.

According to the CIA World Fact book, the population of Guam in 2021 is approximately 170,000. To find the total population of the world, we can use the United Nations' estimate of 7.9 billion people as of 2021. So, the population of countries other than Canada and Guam is:

7.9 billion - 38 million - 170,000 = 7,747,830,000

Now, to find out what percentage of the world's population lives in countries other than Canada and Guam, we divide this number by the total population of the world and multiply by 100:

(7,747,830,000 ÷ 7,900,000,000) x 100 = 97.06%

Therefore, approximately 97.06% of the world's population lives in countries other than Canada and Guam.

Answer:

We can use the formula for the test statistic for a hypothesis test of a single proportion:

z = (p-hat - p) / sqrt(pq/n)

where p-hat is the sample proportion, p is the hypothesized population proportion (0.301 according to Benford's Law), q = 1 - p, and n is the sample size.

Plugging in the values given, we get:

z = (0.2278 - 0.301) / sqrt(0.301*0.699/225) = -2.83

To find the P-value, we need to find the probability that a standard normal distribution is less than -2.83 (since this is a left-tailed test). Using a standard normal table or calculator, we find this probability to be 0.0023.

Therefore, the P-value is 0.0023.

Answer: less

Explanation:

Answer: Around 1,518.7%

Explanation:

To find the percentage, just divide them & multiply it by 100%:

\(\frac{836.34}{55.07}*100 =1518.685309606\)

So, the answer is around 1,518.7%.

Starting with the given equations:

s^2 = t^-1

t^(1/4) = u^(-1/3)

First, we can simplify the second equation by raising both sides to the 4th power:

t^(1/4)^4 = u^(-1/3)^4

t = u^(-4/3)

Substitute this value for t in the first equation:

s^2 = (u^(-4/3))^-1

s^2 = u^(4/3)

Taking the square root of both sides:

s = ± u^(2/3)

Therefore, the value of s in terms of u is s = ± u^(2/3).

The probability that the child will have red hair color is 0.75.

Thus, the probability that a child of these parents will have the blond / blond genotype is 0.25.

Explanation:

It is provided that each parent has the genotype red / blond which consists of the pair of alleles that determine hair color, and each parent contributes one of those alleles to a child.

The possible outcomes for the hair color of the child are:

S = {R/R, R B, B/R and B/B}

There are four possible outcomes.

Compute the probability that the child will have red hair color as follows:

\(P(\text{R})=P(\text{R/R})+P(\text{R/B})+P(\text{B/R})\)

Explanation:

Models of Bureaucracy

Bureaucracies are complex institutions designed to accomplish specific tasks. This complexity, and the fact that they are organizations composed of human beings, can make it challenging for us to understand how bureaucracies work. Sociologists, however, have developed a number of models for understanding the process. Each model highlights specific traits that help explain the organizational behavior of governing bodies and associated functions

The Weberian Model

The classic model of bureaucracy is typically called the ideal Weberian model, and it was developed by Max Weber, an early German sociologist. Weber argued that the increasing complexity of life would simultaneously increase the demands of citizens for government services. Therefore, the ideal type of bureaucracy, the Weberian model, was one in which agencies are apolitical, hierarchically organized, and governed by formal procedures. Furthermore, specialized bureaucrats would be better able to solve problems through logical reasoning. Such efforts would eliminate entrenched patronage, stop problematic decision-making by those in charge, provide a system for managing and performing repetitive tasks that required little or no discretion, impose order and efficiency, create a clear understanding of the service provided, reduce arbitrariness, ensure accountability, and limit discretion

The Acquisitive Model

For Weber, as his ideal type suggests, the bureaucracy was not only necessary but also a positive human development. Later sociologists have not always looked so favorably upon bureaucracies, and they have developed alternate models to explain how and why bureaucracies function. One such model is called the acquisitive model of bureaucracy. The acquisitive model proposes that bureaucracies are naturally competitive and power-hungry. This means bureaucrats, especially at the highest levels, recognize that limited resources are available to feed bureaucracies, so they will work to enhance the status of their own bureaucracy to the detriment of others.

This effort can sometimes take the form of merely emphasizing to Congress the value of their bureaucratic task, but it also means the bureaucracy will attempt to maximize its budget by depleting all its allotted resources each year. This ploy makes it more difficult for legislators to cut the bureaucracy’s future budget, a strategy that succeeds at the expense of thrift. In this way, the bureaucracy will eventually grow far beyond what is necessary and create bureaucratic waste that would otherwise be spent more efficiently among the other bureaucracies

The Monopolistic Model

Other theorists have come to the conclusion that the extent to which bureaucracies compete for scarce resources is not what provides the greatest insight into how a bureaucracy functions. Rather, it is the absence of competition. The model that emerged from this observation is the monopolistic model.

Proponents of the monopolistic model recognize the similarities between a bureaucracy like the Internal Revenue Service (IRS) and a private monopoly like a regional power company or internet service provider that has no competitors. Such organizations are frequently criticized for waste, poor service, and a low level of client responsiveness. Consider, for example, the Bureau of Consular Affairs (BCA), the federal bureaucracy charged with issuing passports to citizens. There is no other organization from which a U.S. citizen can legitimately request and receive a passport, a process that normally takes several weeks. Thus there is no reason for the BCA to

To dissolve a solute in a solvent quickly, Zora should shake it repeatedly.

Shaking the mixture or stirring it vigorously promotes the interaction between the solute and solvent molecules, increasing their chances of coming into contact and facilitating the dissolution process. This agitation helps in breaking down the solute particles and dispersing them evenly throughout the solvent, thereby accelerating the dissolution rate.

Decreasing the pressure or decreasing the surface area would not have a significant impact on the dissolution process. Pressure and surface area primarily affect the rate of dissolution for gases or solid particles exposed to the solvent, but they are not applicable in all scenarios.

Placing the mixture in a refrigerator would slow down the dissolution process rather than speed it up. Lowering the temperature decreases the kinetic energy of the molecules, reducing their movement and the overall rate of dissolution.
