why use non parametric mann-whitney U test rather than parametric independent sample test.
I have a question regarding this because i just complete two question, as one I am using parametric tests, independent sample test, solve the mean selling price of a home with a conservatory different...
We say two permutations f and g commute if fg = gf.
Same as A group G said to be commutative, or ablian if operation *, in addition to be above four axioms, satisfies.
Commutativity, For all x,y belongs to G, we have x*y = y*x
====================================
Can we use this...
We say two permutations f and g commute if fg = gf.
I only know. Permutation (abc)(defgh) have order 15. (123)(45678)
have order 15. I don't know the permutation (123)(45678) in s8 or not.
how to verify it?
===================================
(123)(456) is a permutation has order 3...
Hello, can anyone tell me how to find order 15 in S8.
I only know. Permutation (abc)(defgh) have order 15.
Next, I would think about 8*7*6*5*4*3*2*1 = 13440
Number of permutations, for order 15 in s8. would be
8*7*6*5*4*3*2*1 / 3*5 = 896.
There are 896 permutation of order 15 in...

I know how to find the adjugate of 3x3 matrix. from the defination.
How to find adjugate of 2x2 matrix.
e.g A= ( 1 3 )
______( 2 4 )
adjoint .
I know how to find adjugate and inverse. of 3 * 3 matrix
First . I find matrix of cofactor. from the defination. (n-1)(n-1) matrix * (sign...
Thank you very much. Now I know what I should do next.
Collect all defination of group and connect them using your collection.
One more question. suppose we have a set A (-12,3]. (-x)------(-12)---------0-------------3----------------------------x
They minum for set A is -12, and...
Since x_0 is positive, we might as well ensure that x is positive by letting \delta \leq \frac{x_0}{2} (note we could choose \frac{x_0}{4} or something similar, but half of x_0 is convenient). Hence x > \frac{x_0}{2}, and we have a bound for the term \frac{1}{x^2} since
\frac{1}{x^2} <...
One more question.
How, the supremum, the least upper bound.
Infimum, , supremum.
what is it mean?
Attempt.
for example,
1,. (0,15]
2, {n/2n+1|n belongs to nautral number (N)}
