The following data represent the pH of rain for a random sample
of
12
rain dates in a particular region. A normal probability plot
suggests the data could come from a population that is normally
distributed. A boxplot indicates there are no outliers. The sample
standard deviation is
s=0.332
Construct and interpret a
90%
confidence interval for the standard deviation pH of rainwater
in this region.
