Using the information given and the z-distribution, it is found that:
a) The point estimate of the population proportion is 0.5544.
b) The margin of error is: 0.0320.
c) The interval is: (0.5224, 0.5864).
d) The interpretation of the interval is: we are 95% sure that the true population proportion is between 0.5224 and 0.5864.
What is a confidence interval of proportions?A confidence interval of proportions has the bounds given by the rule presented as follows:
[tex]\pi \pm z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]
In which the variables used to calculated these bounds are listed as follows:
[tex]\pi[/tex] is the point estimate of the population proportion.z is the critical value.n is the sample size.The confidence level is of 95%, hence the critical value z is the value of Z that has a p-value of [tex]\frac{1+0.95}{2} = 0.975[/tex], so the critical value is z = 1.96.
From the sample, the sample size and the point estimate are given as follows:
[tex]n = 929, \pi = \frac{515}{929} = 0.5544[/tex]
The margin of error is given by:
[tex]M = z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]
[tex]M = 1.96\sqrt{\frac{0.5544(0.4456)}{929}}[/tex]
M = 0.0320.
The interval is the point estimate plus/minus the margin of error, hence:
Lower bound: 0.5544 - 0.0320 = 0.5224.Upper bound: 0.5544 + 0.0320 = 0.5864.More can be learned about the z-distribution at https://brainly.com/question/25890103

C. receives from state funding.
D. is expected to receive from all federal funding.
SUBMIT
The EFC is the amount of money that your family is expected to contribute to the cost of your higher education. The correct option is A.
What is EFC?The Expected Family Contribution (EFC) is a gauge of your family's financial stability and is determined in accordance with a legal calculation, according to the FAFSA website. An amount that is equal to a dollar amount will be the EFC.
According to the legal formula, an EFC amount serves as a gauge of a student's family's financial stability.
Therefore, the correct option is A. is expected to contribute to the cost of your higher education.

If sin t = 0.5299 and cos t = 0.8481, then tan t =
Answer:
tan(t) ≈ 0.6248
Explanation:
The definition of tan(t) is ratio of sin(t) to cos(t):
[tex]\displaystyle{\tan t = \dfrac{\sin t}{\cos t}}[/tex]
The value of sin(t) and cos(t) are already given, we just substitute sin(t) = 0.5299 and cos(t) = 0.8481 in the equation:
[tex]\displaystyle{\tan t = \dfrac{0.5299}{0.8481}}[/tex]
Evaluate and we’ll get:
[tex]\displaystyle{\tan t \approx 0.6248}[/tex]
Therefore, tan(t) is 0.6248 (rounded to 4 digits)
Imagine a scatterplot of a class of 20 students showing the relationship between SAT scores on
the x axis and class grade on the y axis, with 19 of the dots showing a clear positive linear
relationship going from the bottom left to the upper right. However, the 20th student (who scored
very high on the SAT) hasn't been going to class or doing the homework and so is flunking the
class. Thus, that datapoint is by itself in the bottom right hand corner of the scatterplot. What
would be the effect on the correlation between SAT and grades if the slacker dropped the class and
his datapoint was deleted?
A. The correlation coefficient (r) would increase.
B. The correlation coefficient (r) would decrease.
C. The correlation coefficient (r) would not change.
D. It is impossible to know.
An outlier will weaken the correlation making the data more scattered so r gets closer to 0. Therefore, if you remove the outlier, the r value will increase (stronger correlation since data will be less scattered).
What is correlation coefficient?
A correlation coefficient is a number between -1 and 1 that tells you the strength and direction of a relationship between variables. In other words, it reflects how similar the measurements of two or more variables are across a dataset.

is the alien theory a scientific claim? Why or why not?
The alien concept is not always a scientific claim because it is not entirely based on true facts, there is no evidence to back it up, and it no longer comes from a trustworthy source.
Scientific claims are statements made in technological know-how that are supported by testing. They make claims similar to those found in other courses, but they may be supported by experimental data you generated as well as the work of other scientists.
Some aspects of the alien theory are scientific in nature. The Drake equation, which was developed by astronomer Frank Drake, is a speculative equation.

From the data you collected for a research paper from 50 individuals, you found that the sample mean (x bar) was 101.5 kilometers, the population mean was 100.2 kilometers minutes, and the standard deviation was 7.6 kilometers. What is the p-value? (Round to 2 decimal places.) 0.33 0 / 1 pts 0.11 (with margin: 0.01)
The p value of the data collected for the research paper is 0.23.
What is the p value?The p value simply implies a number that is calculated from a statistical test which describes how likely one can find a particular set of observations when the null hypothesis is true.
From the information, the sample mean (x bar) was 101.5 kilometers, the population mean was 100.2 kilometers minutes, and the standard deviation was 7.6 kilometers.
The test statistic will be:
= (101.5 - 100.2) / (76 / ✓50)
= 13 / 1.0748
= 1.21
The p value will be:
= 2 × P(z > 1.21)
This is because it's two tailed. The value will be looked in the probability table.
= 2(0.1131)
= 0.23
