Getting Started: Mean Height of a
Population
Getting Started is a fast-paced introduction. Read the chapter for details.
Suppose you want to estimate the mean height of a population of women given
the random sample below. Because heights among a biological population tend
to be normally distributed, a t distribution confidence interval can be used when
estimating the mean. The 10 height values below are the first 10 of 90 values,
randomly generated from a normally distributed population with an assumed
mean of 165.1 centimeters and a standard deviation of 6.35 centimeters
( ) with a seed of 789).
