For this case we have the following expressions:

x \leq-2\\x \geq0

So:

x \leq-2 Indicates all values less than or equal to -2.

That is, from -∞ to -2.

x \geq0 Indicates all values greater than or equal to 0.

That is, from 0 to ∞.

The "or" means that they do not intersect. So, the correct graph is option A.

Answer:

Option A

Solve the problem. A variable x has the possible observations shown below. Possible observations of x: -3 -1 0 1 1 2 4 4 5 Find
svp [43]

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, (\mu) = \frac{\sum X}{n}

                       =  \frac{(-3)+ (-1)+ 0+ 1+ 1+ 2+ 4+ 4+ 5}{9}  

                       =  \frac{13}{9}  = 1.44

Standard deviation of X, (\sigma) =  \sqrt{\frac{\sum (X-\bar X)^{2} }{n-1} }

                            =  \sqrt{\frac{(-3-1.44)^{2}+(-1-1.44)^{2}+......+(4-1.44)^{2}+(5-1.44)^{2} }{9-1} }

                            =  2.603

Now, the z-score corresponding to an observed value of x of 2 is given by;

                  z-score =  \frac{X-\mu}{\sigma}

                               =  \frac{2-1.44}{2.603}  = <u>0.215.</u>
