As n tends to infinity in binomial distribution, it approaches a normal distribution.
As n tends to infinity, the shape of the binomial distribution curve becomes more symmetrical.
The mean and variance of the binomial distribution approach the mean and variance of a normal distribution.
The central limit theorem states that as n approaches infinity, the distribution of sample means approaches a normal distribution.
det(A- lamda*I) = 0 represents the characteristic equation of a matrix A.
It represents finding the eigenvalues of matrix A.
It is used to solve for the values of lambda that satisfy the equation.
The equation is used to determine the behavior of the matrix under certain transformations.
Example: For a 2x2 matrix A, det(A- lamda*I) = 0 gives a quadratic equation to solve for eigenvalues.
SQL query to find Set difference between two tables.
Use the EXCEPT keyword in SQL to find the set difference between two tables.
The EXCEPT keyword returns rows from the first table that are not present in the second table.
Example: SELECT column_name FROM table1 EXCEPT SELECT column_name FROM table2;
K2S hypothesis testing is a statistical method used to compare two groups or samples.
K2S hypothesis testing involves comparing the means of two groups to determine if they are significantly different.
It is commonly used in research studies to test the effectiveness of a new treatment or intervention.
