Answer:
The z-score corresponding to an observed value of x of 2 is 0.215.
Step-by-step explanation:
We are given that a variable x has the possible observations shown below;
Possible observations of X: -3, -1, 0, 1, 1, 2, 4, 4, 5.
Firstly, we will find the mean and the standard deviation of X, i.e;
Mean of X, () =
=
= = 1.44
Standard deviation of X, () =
=
= 2.603
Now, the z-score corresponding to an observed value of x of 2 is given by;
z-score =
= = <u>0.215.</u>

Step-by-step explanation:
From the question we are told that
Matrix is given as
Generally let the change in matrix be given as X
Matlab output
Generally the matrix that makes row 2 of matrix A equal to first row of A multiplied by the negative of the first element of row 2 plus the original row is
