Hey there!
On the horizontal axis, the x-axis, find the point where it says 8.
Then move up to where the y-coordinate is 5.
That is the point (5, 8)
(This basically means- 8 units right and 5 units up)
Let me know if this helps :)
N is an number you make up or your teacher so we need to know what n equals
Answer:
Option (c) is correct.
68% of the data points lie between 10 and 18.
Step-by-step explanation:
Given : a normal distribution with a standard deviation of 4 and a mean of 14
We have to choose the sentence that correctly describes a data set that follows a normal distribution with a standard deviation of 4 and a mean of 14.
Since, given 68% data.
We know mean of data lies in middle.
And standard deviation is distribute equally about the mean that is 50% of values less than the mean and 50% greater than the mean.
So, 68% of data lies
mean - standard deviation = 14 - 4 = 10
mean + standard deviation = 14 + 4 = 18
So, 68% of the data points lie between 10 and 18.
