Question
For the following Box Plot of Flight Arrival Delays select the best answer:8. The first quartile is,a. -40 b. -30 c. -19 d. Zero9. If the Median = - 10, then the mean =a. -10 b. -7.5 c. 0 d. 10
Solution
Without the actual box plot image, it's impossible to accurately answer question 8. The first quartile value is typically found on the box plot itself.
For question 9, it's important to note that the median and the mean are two different measures of central tendency and do not necessarily equal each other. The median is the middle value when the data is ordered from least to greatest, while the mean is the average of all the data points. Without additional information, we cannot determine the mean based on the median. Therefore, none of the options a. -10 b. -7.5 c. 0 d. 10 can be definitively chosen as the correct answer.
