Question
Refer to the accompanying table, which describes results from groups of 8 births from 8 different sets of parents. The random variable \( x \) represents the number of girls among 8 children. Find the mean and standard deviation for the number of girls in 8 births. \[ \text{Click the icon to view the data table.} \] The mean is \( \mu = \square \) girl(s). (Round to one decimal place as needed.) The standard deviation is \( \sigma = \square \) girl(s). (Round to one decimal place as needed.) Note: There are no graphs or diagrams in the image, and further data for calculations require accessing the referenced data table.

**Table of Numbers of Girls and Probabilities** This table presents the probability distribution for the number of girls (x) in a given scenario: | Number of Girls (x) | P(x) | |---------------------|-------| | 0 | 0.006 | | 1 | 0.035 | | 2 | 0.116 | | 3 | 0.216 | | 4 | 0.263 | | 5 | 0.223 | | 6 | 0.103 | | 7 | 0.035 | | 8 | 0.003 | **Explanation of the Table:** - **Number of Girls (x):** This column lists the possible number of girls in the scenario, ranging from 0 to 8. - **P(x):** This column indicates the probability of having exactly x number of girls. Each probability value represents the likelihood of each outcome. **Functions:** - **Print:** Allows you to print the table for offline review. - **Done:** Confirms that you have finished interacting with the table. This table is ideal for understanding probability distributions in various educational or statistical studies.
