Suppose a normal distribution has a mean of 12 and a standard deviation of 4
a value of 18 is how many standard deviations away from the mean?
a -2
b -1.5
c 1.5
d 2

The correct answer is C. 1.5

Step-by-step explanation:

To find this, first find the difference from the value to the mean.

18 - 12 = 6

Now that we have this, divide it by the size of a standard deviation to find how many it is away.

6/4 = 1.5

answer is d-29

step-by-step explanation:

since you didn't include the picture, i can give you the description so you know how to pick the correct answer. the third quartile of a data is always shown in a box plot. in the middle of your graph should be a box. the third quartile is the value that goes with the far right edge of the box.
