I just need help with part D please

### Statistical Probability in Flight Timeliness #### Part 3 of 4 (c) Find the probability that 9 or more of the flights were on time. The probability that 9 or more of the flights were on time is **0.8368**. --- #### Part 3 / 4 [Progress bar indicating completion status of Part 3 out of 4] --- #### Part 4 of 4 (d) Would it be unusual for 10 or more of the flights to be on time? Use a cutoff of 0.05. **It [Choose one] be unusual for 10 or more of the flights to be on time since the probability is [Text box].** --- #### Interaction Buttons - **Check** (Button to verify answers) - **Save for Later** (Button to save the current state of progress) - **Submit Assignment** (Button to submit the completed assignment) --- ### Instructions 1. Review the probability calculation for the scenario where 9 or more flights are on time. 2. Apply the provided cutoff (0.05) to interpret whether 10 or more on-time flights would be considered unusual. 3. Use the dropdown and fill in the appropriate response based on your interpretation of the probability. 4. Use the "Check" button to verify your answers before submitting the assignment.

**Educational Website Transcription** --- ### Lesson: Understanding Probabilities with Real-World Applications **Context**: Your flight has been delayed. At Denver International Airport, 87% of recent flights have arrived on time. A sample of 11 flights is studied. **Task**: Round the probabilities to at least four decimal places. --- #### Part 1 of 4 **(a)** Find the probability that all 11 of the flights were on time. **Answer**: The probability that all 11 of the flights were on time is **0.2161**. --- #### Alternate Answer: The probability that all 11 of the flights were on time is **0.2161**. --- #### Part 2 of 4 **(b)** Find the probability that exactly 9 of the flights were on time. **Answer**: The probability that exactly 9 of the flights were on time is **0.2654**. --- ##### Graphs and Diagrams: The image provided primarily details questions and corresponding answers in text form and does not include any graphs or diagrams. ##### User Interface Description: The interface includes green checkmarks indicating correct answers next to the calculated probabilities. There are also interactive elements such as "Save For Later" and "Submit Assignment" buttons on the bottom right. --- © 2023 McGraw Hill LLC. All Rights Reserved.
