2. Correlation basics Which of the following statements about correlation are true? Check all that apply. If the correlation bet

cluponka [151]

Answer:

The correct statements are: 1, 2, 3, 4 and 5.

Step-by-step explanation:

A correlation coefficient is a mathematical measure of certain kind of correlation, in sense a statistical relationship amid two variables.

It is a statistical degree that computes the strength of the linear relationship amid the relative movements of the two variables (i.e. dependent and independent).It ranges from -1 to +1.

Positive correlation is an association amid two variables in which both variables change in the same direction.

A positive correlation occurs when one variable declines as the other variable declines, or one variable escalates while the other escalates.

Negative correlation is a relationship amid two variables in which one variable rises as the other falls, and vice versa.

If there is any alteration in the value of one variable, the value of the other variable is altered in a fixed proportion. The correlation amid them is known as perfect correlation.

In statistics, a perfect positive correlation is represented by +1 and -1 indicates a perfect negative correlation.

The correlation coefficient is scaleless. This implies that the value of the correlation coefficient does not changes if the scale of one or both the variables are altered.

Thus, the correct statements are: 1, 2, 3, 4 and 5.

Use the equation and type the ordered-pairs. y=3^x

aleksandrvk [35]

The ordered pairs of the equation y = 3^x are (0,1), (1,3) and (2,9)

<h3>How to type the ordered pairs?</h3>

The equation is given as:

y = 3^x

Let x = 0, 1 and 2

y = 3^0 = 1

y = 3^1 = 3

y = 3^2 = 9

So, we have the following ordered pairs (0,1), (1,3) and (2,9)

Hence, the ordered pairs of the equation y = 3^x are (0,1), (1,3) and (2,9)

Which expression is equivalent to Negative 32 Superscript three-fifths?

Sidana [21]

Answer:

$-8$

Step-by-step explanation:

Given: $(-32)^{(\frac{3}{5}) }$

To choose: the correct option

Solution:

Power refers to a number of times, a number is multiplied by itself. Another name for power is exponent.

As per rule of exponents, $(a^m)^n=a^{mn}$

Here,

$(-32)=(-2)^5$

Therefore,

$(-32)^{(\frac{3}{5}) }=[(-2)^5]^{(\frac{3}{5}) }=(-2)^{5(\frac{3}{5}) }$

Here, $a=-2,m=5,n=\frac{3}{5}$

So,

$(-32)^{(\frac{3}{5}) }=[(-2)^5]^{(\frac{3}{5}) }=(-2)^{5(\frac{3}{5}) }=(-2)^3=-8$

Within the United States, approximately 11.25% of the population is left-handed. Of the males, 12.6% are left-handed, compared t

GuDViN [60]

Answer:

There is a 45.05% probability that the selected person is a right-handed female.

Step-by-step explanation:

We have these following probabilities

A 50% probability that a person is a male

A 50% probability that a person is a female.

A 12.6% probability that a male is left-handed.

A 9.9% probability that a female is left-handed.

If a person is selected at random, to find the probability that the selected person is a right-handed female, one would compute:

50% are female.

9.9% of the females are left-handed, so 100-9.9 = 90.1% of the females are right handed.

So

$P = 0.5*0.901 = 0.4505$

There is a 45.05% probability that the selected person is a right-handed female.
