lora16 [44]

If both variables are categorical. We analyze an association through a comparison of conditional probabilities and graphically represent the data using contingency tables (Two-way table).

We have to make the two - way table of the X and Y values.

What is categorical variables ?

A categorical variable (also known as a qualitative variable) in statistics is a variable that may take one of a restricted, and typically fixed, number of potential values, allocating each human or other unit of observation to a specific group or nominal category based on some qualitative feature.
Some variables can be said to be categorical, or they can be treated as such based on the length of their unique values.
For example, if a variable contains only unique values [-2,4,56], you may consider it categorical.
Every unique value in every category variable will result in the creation of a new column.

total purchase price: $27,722.01

Step-by-step explanation:

The price of the car plus tax is ...

$25,625 × (1 +7.5%) = $27,546.88

Adding license and title charges brings the total to ...

$27,546.88 +175.13 = $27,722.01 . . . total purchase price

_____

<em>Additional comment</em>

10% of that, or $2,772.20, will be the required down payment, leaving a balance due of $24,949.81. The payments on a 36-month loan at 9% will be $793.40, for a total loan cost of $28,562.30. Then the full cost of the car, including financing, is $31,334.50. The cost of the financing is $3,612.49.

The probability of observing the experiment result, a sample mean, for example, or something more unusual just by chance if the null hypothesis is true is the definition of "P-Value."

<h3>What is null hypothesis?</h3>

A null hypothesis is a sort of statistical hypothesis which asserts that there is no statistical significance in a particular set of observations.

Using sample data, hypothesis testing is performed to determine the believability of a theory. It really is expressed as H0 and is also known to simply as "null."

Some key features regarding null hypothesis are-

A null hypothesis is a statistical conjecture that claims there is no variation between particular qualities of a population and data-generating process.
The alternate hypothesis asserts the existence of a distinction.
Hypothesis testing allows you to reject the null hypothesis with a particular level of confidence.
If the null hypothesis can be rejected, it lends support to the alternative hypothesis.
The notion of falsity in science is founded on null hypothesis testing.
