I work through an example of finding power of a 1 sample proportion z test which is 2 sided.
I added some annotations to the language of my examples.
Defining the variable:
P: The population proportion of people that travel during the holidays.
With 350(.68)=238 and 350(1-.68)=112 being greater than or equal to 10, the sampling distribution of sample proportions will be approximately Normal. Find free review test, useful notes and more at http://www.mathplane.com
