The mean of a normally distributed dataset is 12, and the standard deviation is 2.
% of the data points lies between 8 and 16.

95.44% of the data lies between 8 and 16.

Step-by-step explanation:

Since, z score or standard score formula is,

Where,

= mean of the data,

= standard deviation,

Let X represents a data point,

So, we have to find out,

P( 8 < X < 16),

Since,

 ( By the z-score table )

Hence, 95.44% of the data lies between 8 and 16.
