Hypothesis Test vs P

This app provides the ability to perform Type I Error hypothesis testing. The null hypothesis and sample size can be specified. Depending on the selected mode, the alpha error or the acceptance or rejection range can be calculated. The different modes offer the possibility of performing right-sided, left-sided or bilateral tests. For this purpose, k1 and/or k2 can be specified for mode I or II. Various modifications can be made to calculate the acceptance and rejection ranges. It is important to note whether X should be greater than/equal to or less than/equal to k. P(X)≤ α is always assumed. The solution is shown step by step. All calculations are saved in history. The final solution can be shared. [ Contents ] - 2 modes to calculate alpha error with right, left or bilateral tests - 4 modes for calculating acceptance and rejection range depending on α - Results are calculated and displayed in detail - History to save input - detailed solution - Natural numbers and decimal numbers are supported depending on the variable - no ads! [ Use ] - There are fields for entering values using a special keyboard - Click on the checkmark button at the bottom right to start the calculation - If values are missing, the corresponding field is highlighted in yellow - If the values are incorrect, the affected field is highlighted in red - a short message explains why a value is incorrect - The entries in the history can be deleted or sorted - When you select an entry in the history, it is automatically loaded for calculation - All history can be deleted at the touch of a button - Solutions can be shared

P-REx Zero Console: Parameterized Runtime Execution (Z3R0 Edition) I just wanted to run one function. RStudio didn’t open. My Wi-Fi disappeared. Cookies were required — tragically, not the snacking kind. So I made this. This is P-REx Zero, a lightweight demo version of the full P-REx app. It’s a stripped-down R console for your iPhone. No cloud. No account. No add-ins. Just R, running offline, like it’s 2004 and deep focus was still fashionable. Whether you’re simulating data from the couch, calculating probabilities at 35,000 feet, or panic-testing t.test() before a meeting, P-REx Zero shows up quietly and does the math. Like a stats TA who won’t judge your p-value or your life choices. What this version does: • Runs a focused set of core R functions • Good for testing, learning, and basic stats • Offline, because life happens • Remembers your variables, even if you don’t • No ads, no feeds, no “smart” tooltips Want more? The full version of P-REx unlocks 99+ functions, extended syntax support, and extra features. But this gets you started. The paid version of P-REx Console can be found here: https://apps.apple.com/ca/app/p-rex-console/id6743998835 I built it to run one line of code. Now I use it to avoid everything else.
