A normal distribution has a mean of 135 and a standard deviation of 8. Find the Z-score for a data value of 118.
Round to two decimal places

The z-score will be -2.125

Step-by-step explanation:

To calculate z-score, use the mean and standard deviation. The equation is

z=value-mean

/standard deviation

step-by-step explanation: yes

options a,b,c are the right answer.

step-by-step explanation:

a linear parent function is always represented as y = x

if we write this function in the form of y=mx+c

⇒

or  

now if we plot a graph we will find these characteristics:

1) y intercept of the graph is zero so its a straight line passing through origin.

2) as we can see in both the forms of function written, values of x and y may be either positive or negative for the positive slope means points on the graph are either in first quadrant or in third one.

3) it's slope is one.
