library(infer)Suppose the mean bone density for a 65-year old woman is normally distributed with mean 809 mg/cm3 and standard deviation of 140 mg/cm3 (these are actually pretty accurate numbers).
What bone densities correspond to the 5th, 10th, 50th, and 99th percentiles of this distribution?
The densities of three types of wood are below:
What is the probability that a random 65-year old woman has bones less dense than each of these three woods?
What is the probability that, for a group of 10 randomly sampled 65-year old women, the mean bone density of the group is less dense than each of these three woods?
Explain the differences between your answers in Exercise 2 and 3.
