This can also be written as the following.
Ho: mean per student per year funding for New Jersey = mean per student per year funding for the USA NOTE: There are many ways to write out Ho. Hypothesis: The mean per student per year funding in New Jersey is significantly greater than the average per student per year funding over the entire USA. If you do not have this information, it is sometimes best to use the t-test. To run a z-test, it is generally expected that you have a larger sample size (30 or more) and that you have information about the population mean and standard deviation. Using the dataset, you would need to first calculate the sample mean. NOTE: This entire example works the same way if you have a dataset. Use the z-test and the correct Ho and Ha to run a hypothesis test to determine if New Jersey receives significantly more funding for public school education (per student per year).
Next, suppose you collect a sample (n = 100) and determine that the sample mean for New Jersey (per student per year) is $8801. You know that the USA mean public school yearly funding is $6300 per student per year, with a standard deviation of $400. Suppose it is up to you to determine if a certain state receives significantly more public school funding (per student) than the USA average.
