The mean age of a first-time parent is 28.2 years old. Assume 𝜎𝜎 =
4.3 years and that these ages are
normally distributed.
1a. Draw a sketch of the population distribution with the values of
𝜇𝜇, 𝜇𝜇± 𝜎𝜎, 𝜇𝜇± 2𝜎𝜎, 𝑎𝑎𝑎𝑎𝑎𝑎 𝜇𝜇± 3𝜎𝜎
labeled.
b.Find the probability that a random first-time parent is more
than 25 years
