Not so fun fact you need to install ISwR packages for this code to do anything. I thought it was built in and couldn't understand why it wouldn't work.

Analysis
Pemax is described using a model that is additive in age, weight, bmp, and fev1. Using information from the Cystic Fibrosis Database in ISwR. I ran a summary as suggested in the book to try to understand what was actually written there and this is the information gleaned.

  A. Consider a population consisting of the following values, which represents the number of ice cream purchases during the academic year for each of the five housemates. 8, 14, 16, 10, 11 a. Compute the mean of this population.  11.8 b. Select a random sample of size 2 out of the five members.  8 and 14 c. Compute the mean and standard deviation of your sample.  11 d. Compare the Mean and Standard deviation of your sample to the entire population of this set (8,14, 16, 10, 11). Mean of sample is less then mean of population. standard deviation is smaller as well.  Suppose that the sample size  n  = 100 and the population proportion  p  = 0.95. Does the sample proportion  p  have approximately a normal distribution? yes Since p = .95, q = .05.  p * n = .95 * 100 = 95 q * n = .05 * 100 = 5 What is the smallest value of  n  for which the sampling distribution of  p  is approximately normal?   6 beca...
