St. West High School requires that students are assigned an average of 2.5 hours of homework each night.
The school board believes that the average amount of time per night is not 2.5 hours, so they decide to
take a random sample of 16 students to see if there is convincing evidence to support their suspicion. The
board finds that the sample of students were assigned an average of 2.8 hours of homework per night with
a standard deviation of 0.8 hours.
The board want to use these sample data to conduct a t test on the mean. Assume that all conditions for
inference have been met.
Calculate the test statistic for their test.

Explanation:

The emotional effect on one individual. This is the information that you get from this poem that might not be conveyed as effectively in a nonfiction article about the relocation of Japanese Americans during World War II.

What are the Evidence of this maltreatment?

Evidence of this maltreatment is shown in the letter when both the waitress and the policemen did not want to help the boys simply because they were Japanese and they made this feeling known in a hostile and rude way.

There was a massive labour shortage in the US in WW2 because many men had gone off to fight the war. When War broke out, many Japanese were interned in camps around the US and whilst there, they supplemented the need for labor in the US.

They harvested crops and constructed infrastructure and even repaired roads and rail lines. All these were important to the US war effort as well as the domestic economy and this was what the boys in the letter was referring to when he said they came to help with the labor shortage.

Therefore,  a nonfiction article about the relocation of Japanese Americans during World War II.

A small school with 60 total students records how many of their students attend school on each of the 180
days in a school year. The mean number of students in attendance daily is 55 students and the standard
deviation is 4 students. Suppose that we take random samples of 5 school days and calculate the mean
number of students ĉ in attendance on those days in each sample.
Calculate the mean and standard deviation of the sampling distribution of

Answers

Answer:

The answer is below

Explanation:

Given that the mean of the attendance of the population (μ) = 55 students, and the standard deviation (σ) = 55 students

If repeated random samples of a given size n are taken from a population with a population mean of μ and the population standard deviation of σ,  then the mean of the sample distribution ([tex]\mu_x[/tex]) is population mean μ, while the standard deviation of the sample distribution ([tex]\sigma_x[/tex]) is the population standard deviation divided by the square root of the sample size.

Given a random sample (n) of 5 days, hence:

mean of sampling distribution ([tex]\mu_x[/tex]) = μ = 55 students

standard deviation of the sampling distribution = [tex]\sigma_x[/tex] = [tex]\frac{\sigma}{\sqrt{n} }=\frac{4}{\sqrt{5} } =1.79[/tex]

Which statement is not true about the 95% confidence level?
5 point
Confidence intervals computed by using the same procedure will include the true
population value for 95% of all possible random samples taken from the population.
O
The procedure that is used to determine the confidence interval will provide an
interval that includes the population parameter with probability of 0.95.
O
The probability that the true value of the population parameter falls between the
bounds of an already computed confidence interval is roughly 95%.
If we consider all possible randomly selected samples of the same size from a
population, the 95% is the percentage of those samples for which the confidence
interval includes the population parameter.

Answers

Answer:

Explanation: which of the following is true about a 95% confidence interval of the mean: 95 out of 100 sample means will fall within the limits of the confidence interval. 95 out of 100 confidence intervals will contain the population mean. 95% of population means will fall within the limits of the confidence interval.

Literally, the confidence interval of a dataset gives the probability the value of a given parameter will fall within a range of value.

The statement that is not true about 95% confidence interval is option (c).

There are several confidence intervals. The most common intervals are:

[tex]90\%[/tex] confidence interval[tex]95\%[/tex] confidence interval[tex]99\%[/tex] confidence interval

The name of these intervals does represent the probability that the value of a given parameter will fall within the range of values close to the mean.

Take for instance, the 95% confidence interval.

The 95% of 95% confidence interval does not mean that the probability that the value of a given parameter will fall within a range of value close to the mean will be 95% or close to 95% or roughly 95%.

This means that option (c) is not true about 95% confidence interval

The Jews and Christians in the region were at first probably ambivalent, if not indifferent or hostile, to the change in the dynastic succession from Marnluk to Ottoman
sultans who exercised sovereignty over their lives, but their fortunes were about to improve under the new regime. The Ottoman sultans were still winning victories
against European armies on the battlefield, and the presence of Christians so distant from the war zone in Central Europe must not have felt particularly threatening or
Indeed important (beyond the collection of their taxes) to most Ottoman officials posted in the Arab lands. In the case of the Sephardic Jews, the Ottoman sultans
welcomed them into their realm as potentially revenue-producing subjects. Most importantly, the political tradition honored by the Ottoman sultans was to grant
autonomy to the various religious groups of their empire. This afforded the Christians and Jews in the Ottoman Middle East fairly wide ranging freedoms and allowed
them to recover some of the losses they had endured under the Mamluks, including the right to repair damaged churches and synagogues and, in a few cases,
permission to build new ones."

A: The Ottoman millet system, an arrangement designed to utilize the economic contributions of non-Muslim groups within the empire while granting

B: The Ottoman practice of devshirme, a military levy of Christian boys who would be converted to Islam and trained as Ottoman Janissary soldiers or
bureaucrats in state service
C: The Ottoman practice of farming out the collection of taxes to local private individuals (some of them non-Muslim), because of the shortage of
trained government financial officials
D: The Ottoman sultans continued powers of granting final approval for any high-ranking appointment of a non-Muslim religious leader, including the
power to approve patriarchs and bishops of the various Christian communities and chief rabbis of the Jewish community

Answers

Answer: A: The Ottoman millet system, an arrangement designed to utilize the economic contributions of non-Muslim groups within the empire while granting them limited autonomy to organize their communal affairs under their own religious leaders

Explanation:

The second paragraph talks about how the Ottomans welcomed other groups into their areas as potentially revenue-producing subjects and allowed them wide-ranging freedoms. The best support for this would be the Millet System.

By this system, the Ottomans allowed Muslim, Christian and Jewish communities the right to govern themselves provided them accept Ottoman superiority. This drew more people into the empire and allowed the Ottomans to benefit from the economic contributions of these groups.
