The value of r indicates the negative correlation.

<h2>Given </h2>

Rikki decided to collect data to determine if a runner's time and speed are correlated.

She determined the data to have a correlation coefficient of -0. 5.

<h3>What is the correlation coefficient?</h3>

The correlation coefficient is a statistical measure that calculates the strength of the relationship between the relative movements of the two variables.

She determined the data to have a correlation coefficient of -0. 5.

Here, the coefficient is negative which is -0.5.

This correlation coefficient indicates that there exists a weak negative correlation between the runner’s time and the speed.

This relation is negative because the correlation coefficient is negative.

Hence, The value of r indicates the negative correlation.

What is subjective?? (Science)
natita [175]

Answer:

Hypotheses are always made by one individual or by a limited group of scientists, and are therefore subjective—based on the prior experience and processes of reason employed by those individuals, rather than solely on objective external process. 

According to this view, human attitude is associated with human sciences; but as far as natural science is concerned there is no scope for any subjective elements. Scientific knowledge is purely objective, and it is an objective description of the real structure of the world.

Step-by-step explanation:

Pertaining to or characteristic of an individual; personal; individual: a subjective evaluation.

Phrase collocation :

  1. subjective idealism
  2. subjective test
  3. subjective brightness

Bilingual example Used as an adjective (adj.) :

  1. Whatever is subjective in you, is the truth.
  2. The answer is not easy and, in this case, it is largely subjective .
  3. Marxism is not true and is not science, but so what? The hermeneuticians tell us that nothing is objectively true, and therefore that all views and propositions are subjective.
  4. His arguments were never subjective.
  5. He took a subjective view of the problem.
  6. Grading of oral tests is quite subjective.

monitta

Answer:

lower 95% Cl is 0.292

Step-by-step explanation:

p^ = 0.4783

n = 23

for 95% Cl,

z = 1.9600

Inputting all the available data into P as attached below

LCL = 0.292

UCL = 0.670

therefore, lower 95% Cl = 0.292

HELP ME PLEASE!!!!!!
Deffense [45]

Answer:

  -2x +4

Step-by-step explanation:

We can write the polynomial p(x) in terms of the factors (x+2) and (x-3) as ...

  p(x) = (x+2)(x-3)q(x) +ax +b

Where ax+b is the remainder from division by x^2 -x -6 = (x+2)(x-3). The values of 'a' and 'b' can be found from ...

  p(-2) = 8 = -2a +b

  p(3) = -2 = 3a +b

Subtracting the first equation from the second gives ...

  (3a +b) -(-2a +b) = (-2) -(8)

  5a = -10

  a = -2

Then the first equation tells us ...

  8 = -2(-2) +b

  4 = b

So, the remainder from division by (x^2 -x -6) is (-2x +4).
