Introduction to Normal Distributions

Question 24 • CR - Algebra 2 26-27 - S2

Which of the following did you include in your response? Check all of the boxes that apply.

Answer

The z-score for 2,500 g is –2.

According to the empirical rule, 95% of babies have a birth weight of between 2,500 g and 4,500 g.

5% of babies have a birth weight of less than 2,500 g or greater than 4,500 g.

Normal distributions are symmetric, so 2.5% of babies weigh less than 2,500g.
