Answer:

mean

Step-by-step explanation:

Normal distribution curves Is a distribution curve having different mean values with a standard deviations

the correct option: mean

A normal distribution curve is standardized as follows:

(a) The mean value of the unstandardized curve is made the origin, thus making the mean value, x, zero.

(b) The horizontal axis is scaled in standard deviations. This is done by letting z= x−x/ σ , where z is called the normal standard variate, x is the value of the variable, x is the mean value of the distribution and σ is the standard deviation of the distribution.
