If both variable in a correlational study are non-numerical, the data can be organized in a matrix and then analyzed using a Chi-square hypothesis test.
A correlational study design investigates relationships between two variables (or more) without the researcher controlling or manipulating any of them.
Chi-square test for hypothesis tests about whether your data is as expected. The basic idea behind the test is to compare the observed values in your data to the expected values that you would see if the null hypothesis is true.
The Chi-square statistic compares the size of any discrepancies between the expected results and the actual results, given the size of the sample and the number of variables in the relationship.
Hence if both variables in a correlational study are non-numerical, the data can be organized in a matrix and then analyzed using a Chi-square hypothesis test.

If X1 , X2 , X3 and X4 are (pairwise) uncorrelated randomvariables, each having mean 0 and variance 1, compute thecorrelations coefficient of(a) X1 + X2 and X2 + X3 ;(b) X1 + X2 and X3 + X4
The correlation coefficient of
(a) X1 + X2 and X2 + X3 would be 1/2.
(b) X1 + X2 and X3 + X4 would be 0.
What is the correlation in statistics?
Correlation is a statistical measure (a number) that describes the magnitude and direction of a relationship between two or more variables. A correlation between variables, on the other hand, does not imply that a change in one variable is the cause of a change in the values of the other variable.
(a) X1 + X2 and X2 + X3.
We have
Cov(X1 + X2, X2 + X3) = Cov(X1, X2) + Cov(X1, X3) + Cov(X2, X2) + Cov(X2, X3)
= 0 + 0 + Var(X2) + 0
= 1.
We know that
Var(X1 + X2) = Var(X1) + Var(X2) + 2 Cov(X1, X2) = 1 + 1 + 2 · 0 = 2.
Similarly, Var(X2 + X3) = 0. So the correlation between X1 + X2 and X2 + X3 is
[tex]=\frac{Cov(X1+X2, X2+X3)}{\sqrt{Var(X1 + X2) Var(X2 + X3)} }\\\\=\frac{1}{\sqrt{2.2} }\\\\=\frac{1}{2}[/tex]
(b) X1 + X2 and X3 + X4.
Since
Cov(X1 + X2, X3 + X4) = Cov(X1, X3) + Cov(X1, X4) + Cov(X2, X3) + Cov(X2, X4)
= 0 + 0 + 0 + 0
= 0,
the correlation between X1 + X2 and X3 + X4 is 0.
Hence, the correlation coefficient of X1 + X2 and X2 + X3 would be 1/2
and X1 + X2 and X3 + X4 would be 0.

Two cards are dealt from a shuffled deck. What is the probability that the first card is an ace and the second card is a face card or a ten?
The probability that the first card is an ace and the second card is a face card is 1.78% and 12/52 respectively.
What is the probability of cards?
Probability is measured by counting and using basic math, such as addition and division. For example, you can multiply the number of spades in a complete deck (13) by the total number of cards in the deck (52) to get the probability of drawing a spade at random: 13 in 52, or 25%.
If you are dealt two cards successively from a standard 52-card deck, find the probability of getting an ace card on the first card and a face on the second.
you want to draw an ace. There are 4 aces out of the 52 cards in the deck so the probability of drawing an ace = 4/52.
So, the combined probability [tex](\frac{12}{52}) . (\frac{4}{52}) = (\frac{3}{13}) . (\frac{1}{13}) = (\frac{3}{169})[/tex]
= 1.78%.
The probability of a face card on the second draw = 12/52 because there are 12 face cards (J, Q, K x 4 of each) and 52 cards in the deck.
Hence, the probability that the first card is an ace and the second card is a face card is 1.78% and 12/52 respectively.

How does Hamlet's view of death change throughout the play?.
Being afraid of the unknown prevents Hamlet from using death as a solution to end his difficulties.
Hamlet's perspective on death changes as he comes to terms with the fact that it is inevitable and he isn't sure he wants to experience it since death might not be preferable to life. Hamlet repeatedly longs for death to put an end to his suffering due to his sadness and agony, but he hesitates since death is forbidden in the Christian religion for fear of being sentenced to eternal torment in hell.We also learn that since another factor contributing to Hamlet's terrible demise was his inability to "do" rather than just "be." His speech, which is primarily about death, demonstrates his propensity to reflect rather than act.This is how Hamlet's view of death changes throughout the play.

TRUE/FALSE: there is a basis of rn consisting of eigenvectors of a, then a is diagonalizable. TRUE/FALSE: if a is diagonalizable, then a is invertible.
If Rn has a basis of eigenvectors of A, then A is diagonalizable.
This statement is true.
If A is diagonalizable, then A is invertible.
This statement is false.
What is diagonalizable matrix?
If there is an invertible matrix P and a diagonal matrix D such that P^-1AP=D, or alternatively A=PDP^-1, then the square matrix A is said to be diagonalizable or non-defective in linear algebra.
If Rn has a basis of eigenvectors of A, then A is diagonalizable.
This statement is true.
In this case we can construct an invertible matrix P.
If A is diagonalizable, then A is invertible.
This statement is false.
It’s invertible if it doesn’t have a zero as eigen value but this doesn’t affect diagonalizabilty.

Sami is making necklaces for a craft show. each necklace is 33.4 centimeters long. if she has 233.8 centimeters of cord, how many necklaces can Sami make?
Sami can make 7 necklaces from the cord
What is a length?Length is defined as the measurement or extent of something from end to end
To find the number of necklaces Sami can make
We divide the Total centimeter of chord with the centimeter of one cord
Total cord=233.8centimter
Each necklace = 33.4centimeters
Therefore, Total cord/Each necklace
=233.8/33.4
=7necklaces
Hence, Sami can make 7 necklaces from 233.8centimeters of cord

Point (-3,5) is a solution to the system of inequalities
What is inequality?
An inequality in mathematics depicts the connection between two values in an algebraic statement that are not equal. One of the two variables on the two sides of the inequality may be greater than, greater than or equal to, less than, or less than or equal to another value, according to inequality signals.
For this case, what we must do is find a point that meets both inequalities.
