Welcome to the Interactive Hypothesis Testing app!
This app allows you to interact with hypothesis tests, including t-tests and z-tests.

You can adjust parameters to see how the test statistic and p-value change, and make decisions based on the results.

The purpose of this app is to help users understand hypothesis testing by visually demonstrating: - How to set up test parameters (sample size, sample mean, etc.) - The calculation of the test statistic - The decision-making process based on the p-value

Interactive Features: - Sliders for setting sample size, sample mean, standard deviation, and significance level. - Real-time calculation of the test statistic (t or z) and p-value. - Visual representation of the test statistic on a normal distribution plot.

The test statistic (t or z) is computed using the formula:

test_stat <- (sample_mean - pop_mean) / (sample_sd / sqrt(sample_size))
p_value <- 2 * (1 - pnorm(abs(test_stat)))

This code is executed when the sliders are adjusted to update the test statistic and p-value dynamically.

This app helps users visualize the results of hypothesis testing in a simple and interactive way.
It is useful for students, professionals, and anyone wanting to better understand hypothesis testing.
