Which sentence correctly describes a data set that follows a normal distribution with a standard deviation of 4 and a mean of 14?
OA. 68% of the data points lie between 10 and 14.
B. 68% of the data points lie between 8 and 12.
OC. 68% of the data points lie between 10 and 18.
OD. 68% of the data points lie between 10 and 16.

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.
