Answer:

Statisticians use z-scores to divide the area under a curve the way people use a knife to cut pizza.

Step-by-step explanation:

Statisticians use z-scores to divide the area under a curve the way people use a knife to cut pizza.

z-score:

  • A z-score is a numerical measurement which is measured in terms of standard deviations from the mean.
  • Formula:

[tex]z_{score} = \displaystyle\frac{x-\mu}{\sigma}[/tex]

  • If a z-score is 0, it tells that the data point is same as the mean.
  • Area under the normal curve is 1.
