State
Make sure to state what your parameters (p1 and p2) mean in context!
Plan - One-sample z-interval for p
Random sample: Must be determined by you. Is this a random sample or random assignment in an experiment?
10% rule: Must be determined by you. Is your sample size smaller than 10% of the population?
Calculate
To find our critical z* value, you can use the inverse normal function on your calculator or use a table with critical values.
Conclude
Please keep in mind that this conclusion is a generic conclusion based on the values put into the table, but will not always reflect what a proper conclusion should look like in context.
