Hypothesis Testing for a Mean - Single Sample

This app enables students to visually explore hypothesis testing for a single sample mean, offering interactive controls to set the sample size, mean, standard deviation, and significance level. Users can adjust these parameters to generate a graph displaying the critical region, p-value, and comparison between the sample mean and the null hypothesis mean, facilitating a deeper understanding of hypothesis testing dynamics.

Single Sample Mean Hypothesis Test

Select a test and enter the sample statistics to perform a hypothesis test.

Test Parameters:

Choose a null hypothesis \( \ H_o \ \) and significance level: \(\ \alpha \ .\)

\( H_o: \ \mu_o = \ \)
3.50     
\( \alpha = \ \)
0.05     

Sample statistics:

Set sample size, mean, and standard deviation:

\( \ n = \ \)
