z tests for percentages

This test can be used if:

• The data is a simple random sample from the population of interest
• The sample size is large
• A qualitative variable of interest summarized by percentages
• Can use a box with tickets of 1s and zeros to represent the population If an observed value is too many SEs away from the expected value, it is hard to explain by chance.

c tests for averages
