1. The problem statement, all variables and given/known data Which of the following is/are likely to show normal distribution? A) Numbers of cervical vertebrae in different species of mammals B) Age distribution of children in school C) Number of fruits in mango trees in an orchard D) Fasting blood glucose levels of healthy people E) Diameters of pencils manufactured in a factory 2. Relevant equations 3. The attempt at a solution A normal distribution graph is bell-shaped,so A) can't be true ,cause all mammals have the same number of cervical vertebrae and I guess E)would also not show a normal distribution cause the pencils manufactured would mostly be of the same diameter. I'm having trouble deciding between B),C) and D). would really appreciate a quick response. Thank you.
