Question
**Trivia Quiz** The probabilities that a player will get 6–11 questions right on a trivia quiz are shown below. | \( X \) | 6 | 7 | 8 | 9 | 10 | 11 | |-----------|-----|-----|-----|-----|-----|-----| | \( P(X) \) | 0.05 | 0.2 | 0.4 | 0.1 | 0.15 | 0.1 | **Explanation:** This table displays the probabilities associated with a player correctly answering a specific number of questions on a trivia quiz. The row labeled \( X \) represents the number of questions answered correctly, ranging from 6 to 11. The row labeled \( P(X) \) provides the probability of each outcome. For example, the probability of a player answering exactly 8 questions correctly is 0.4. **Interactive Section:** - **Send data to Excel:** Click this button to export the probability data into an Excel file for further analysis. **Task:** - **Part 1 of 3:** - **Find the mean.** Do not round your answer. - **Mean: \( \mu = \square \)** Use this section to calculate the expected value (mean) of the number of questions answered correctly based on the given probabilities.
