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>

A straight line has equation 4y-5x=2 work out the gradient of this line
PilotLPTM [1.2K]

Answer:

gradient = \frac{5}{4}

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope (gradient) and c the y- intercept )

Given

4y - 5x = 2 ( add 5x to both sides )

4y = 5x + 2 ( divide the terms by 4 )

y = \frac{5}{4} x + \frac{1}{2} ← in slope- intercept form

with gradient m = \frac{5}{4}
