Final answer:
To find a t statistic or Z statistic in hypothesis testing, follow these steps: enter data, select the appropriate test, enter parameters, choose the alternative hypothesis, calculate the test statistic and p-value, optional: visually represent the results.
Step-by-step explanation:
To find a t statistic or Z statistic in hypothesis testing, the process varies slightly depending on the calculator or software you are using. However, the general steps are as follows:
- Enter the data into a list on your calculator or software.
- Select the appropriate test, either a z-test or a t-test, depending on whether you know the population standard deviation or not.
- Enter the necessary parameters, such as the null hypothesis mean, sample mean, sample size, and standard deviation.
- Choose the desired alternative hypothesis (greater than, less than, or not equal to).
- Calculate the test statistic and p-value.
- Optional: visually represent the results with a graph.
