If a scatterplot of standardized, bivariate data displays data that are mostly lying in the upper left and lower right-hand quadrants, then the Pearson correlation is typically going to be negative. True
False

Answers

If a scatterplot of standardized, bivariate data displays data that are mostly lying in the upper left and lower right-hand quadrants, then the Pearson correlation is typically going to be negative. The above statement is false.

Bivariate data:

Bivariate data involves studying and comparing two separate variables. For example, a researcher may record how long it takes people to complete a crossword puzzle while measuring the stress levels of the participants. In this example, the two variables that the researcher is examining are time and stress.

Scatterplots:

Scatterplots display these bivariate data sets and provide a visual representation of the relationship between variables. In a scatterplot, each point represents a paired measurement of two variables for a specific subject, and each subject is represented by one point on the scatterplot.

When the points on a scatterplot graph produce a lower-left-to-upper-right pattern, we say that there is a positive correlation between the two variables. This pattern means that when the score of one observation is high, we expect the score of the other observation to be high as well, and vice versa.

When the points on a scatterplot graph produce a upper-left-to-lower-right pattern, we say that there is a negative correlation between the two variables. This pattern means that when the score of one observation is high, we expect the score of the other observation to be low, and vice versa.

In statistics, the Pearson correlation coefficient ― also known as Pearson's r, the Pearson product-moment correlation coefficient (PPMCC), the bivariate correlation or colloquially simply as the correlation coefficient ― is a measure of linear correlation between two sets of data. It is the ratio between the covariance of two variables and the product of their standard deviations; thus, it is essentially a normalized measurement of the covariance, such that the result always has a value between −1 and 1. As with covariance itself, the measure can only reflect a linear correlation of variables, and ignores many other types of relationships or correlations. As a simple example, one would expect the age and height of a sample of teenagers from a high school to have a Pearson correlation coefficient significantly greater than 0, but less than 1 (as 1 would represent an unrealistically perfect correlation).

The Pearson correlation method is the most common method to use for numerical variables; it assigns a value between − 1 and 1, where 0 is no correlation, 1 is total positive correlation, and − 1 is total negative correlation. This is interpreted as follows: a correlation value of 0.7 between two variables would indicate that a significant and positive relationship exists between the two. A positive correlation signifies that if variable A goes up, then B will also go up, whereas if the value of the correlation is negative, then if A increases, B decreases.

A statistical measurement known as a p-value is employed to check a hypothesis' validity against actual data.

A p-value calculates the likelihood of getting the outcomes that were observed, presuming that the null hypothesis is correct.

The statistical significance of the difference that was found increases with decreasing p-value.

The p-value, used in null-hypothesis significance testing, represents the likelihood that the test findings will be at least as extreme as the result actually observed, assuming that the null hypothesis is true.

The integers when product of two consecutive odd integers is 21 more than twice the larger

integer are 5 and 7.

How to calculate the integer?

Let the integers be x and x + 2. Since the product of two consecutive odd integers is 21 more than twice the larger integer. This will be:

x(x + 2) = 2(x + 2) + 21

x² + 2x = 2x + 4 + 21

x² + 2x = 2x + 25

Collect like terms.

x² + 2x - 2x - 25

x² - 25

x² - 5²

= (x - 5)(x + 5)

x - 5 = 0

x = 0 + 5

x = 5

The higher number will be:

= x + 2

= 5 + 2

It's better to use adjusted R-squared than simple R because the adjusted R-squared is adjusted for the number of variables and sample size whereas simple R has different values for each size.

Adjusted R-squared considers and tests different independent variables against the model and R-squared does not.

Many investors prefer adjusted R-squared because adjusted R-squared can provide a more precise view of the correlation by also taking into account how many independent variables are added to a particular model against which the stock index is measured.

The unadjusted R-squared increases or stays the same as more variables are included, whereas the adjusted R-squared is adjusted for the number of variables and large sample size.

Adjusted R-squared is calculated for multiple explanatory variables and R-squared value is calculated for only one explanatory variable.

Take the minutes as 'x' they are and the remaining credit as 'y' it is;

The equation will be because it is a linear function:

Y - y1 = m(x - x1)

The statement which is true about the two equilateral triangles is b)The two triangles are the same shape but not the same size. So, correct option is b.

In calculation, a symmetrical triangle is a triangle where every one of the three sides have a similar length. In the natural Euclidean calculation, a symmetrical triangle is likewise equiangular; that is, every one of the three inward points are additionally compatible to one another and are each 60°. It is likewise an ordinary polygon, so it is additionally alluded to as a normal triangle.

Some of hypotheses which are made sense of utilizing symmetrical triangle:

Morley's trisector hypothesis expresses that, in any triangle, the three marks of convergence of the contiguous point trisectors structure a symmetrical triangle.Napoleon's hypothesis expresses that, in the event that symmetrical triangles are built on the sides of any triangle, either all outward, or all internal, the focuses of those symmetrical triangles themselves structure a symmetrical triangle.

The side length of the primary symmetrical triangle is 3 inches.The side-length of the second symmetrical triangle is 4 inches.Since both the triangles are symmetrical triangles, in this way they have same shape.

Be that as it may, the two triangles have different side lengths in this way they have different size.

Number of customers that purchase doughnuts = 225

Proportion of customers who made additional purchase = 36%

The above parameters mean that:

Proportion of customers who made additional purchase = 36% of The total number of customers

Using the above as a guide, we have the following equation

event c: a house belongs to the third;

event g: a house has an attached garage.

20% of the houses in the first county,

⇒ P(a) = 20%

30%  of the houses in the second county

⇒ P(b) = 30%

50%  of the houses in the first county.

⇒ P(c) = 50%

a garage is attached to 70% of the houses in the first county,

⇒ P(a ∩ g) = 70%

a garage is attached to 80% of the houses in the second county

⇒ P(b ∩ g) = 80%

and a garage is attached to 90% of the houses in the third county.

⇒ P(c ∩ g) = 90%

We need to find the probability that a house belongs to the second county, knowing that it has a garage attached to it.

i.e., P(b ∩ g) which is 80% = 0.8

Therefore, the probability that a house belongs to the second county, knowing that it has a garage attached to it is 0.8

Answers

The equation that demonstrates how to determine how much money Maria will have in her savings account the following week is (B) the amount in savings the following week = $680 + $25.

What are equations?

A mathematical statement known as an equation is made up of two expressions joined together by the equal sign.

A formula would be 3x - 5 = 16, for instance.

When this equation is solved, we discover that the value of the variable x is 7.

So, the correct equation will be:

We know that Maria puts $25 every week into her savings account.

We also know that she has $680 in her account.

Now, to get the amount that will be in her savings account next week will be:
$680 + $25

Therefore, the equation that demonstrates how to determine how much money Maria will have in her savings account the following week is (B) the amount in savings the following week = $680 + $25.
