Question
Transcribed Image Text:**Title: Assessing Firmware-Related Pacemaker Malfunctions**
**Introduction:**
In a study involving 7707 cases of heart pacemaker malfunctions, investigations revealed that 333 of these cases were attributed to issues with the firmware—software that is programmed into the device. Understanding the impact and probability of such failures is crucial for ensuring the reliability and safety of pacemakers.
**Problem Statement:**
Consider a scenario where the firmware of pacemakers is being tested. In this trial, three pacemakers are randomly selected from a batch of 7707. The entire batch is accepted if no failures are detected during this testing phase. The primary question is: What is the probability that the firmware in the entire batch will be accepted under these conditions? Additionally, assess whether this acceptance procedure is likely to result in the entire batch being accepted.
**Solution:**
The probability of accepting the batch is calculated based on the test results for the selected pacemakers.
**User Input:**
- **Probability Calculation Box:** An input field where users can calculate and input the probability.
- **Procedure Likelihood Assessment:** A dropdown menu allows users to select an assessment of the likelihood (e.g., "Likely," "Unlikely") of the entire batch being accepted based on the calculated probability.
**Instructions for Calculation:**
- Calculate the probability to three decimal places.
- Determine the likelihood of batch acceptance based on the probability.
**Note:**
These exercises are designed to help students understand the practical applications of probability in real-world scenarios, particularly in medical device reliability.
