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.

Use the sample data and confidence level given below to complete parts a through d.
A research institute poll asked respondents if they felt vulnerable to identity theft. In the poll, n=929 and x=515 who said yes. Use a 95% confidecne level.
A. find the best point of estimate of the population of portion p.
B. Identify the value of the margin of error E.
E= round to four decimal places as needed.
C. Construct the confidence interval.
_ < p <_ round to three decimal places.
D. Write a statement that correctly interprets the confidence interval.
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

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.
