Math Problem Statement
Question content area top Part 1 A successful basketball player has a height of 6 feet 1111 inches, or 211211 cm. Based on statistics from a data set, his height converts to the z score of 5.175.17. How many standard deviations is his height above the mean?
Solution
The z-score represents how many standard deviations a particular value is above or below the mean in a dataset. In this case, the z-score of 5.17 indicates that the player's height is 5.17 standard deviations above the mean.
To interpret:
- Z-score =
- Where:
- X is the individual value (the player's height).
- is the mean (average) height of the data set.
- is the standard deviation of the data set.
- Where:
Given that the z-score is 5.17, it means the player’s height is 5.17 standard deviations above the mean height in the data set.
Conclusion:
The player's height is 5.17 standard deviations above the mean.
Would you like further details on z-scores or how to calculate them in general?
Here are some related questions you might find useful:
- What does a negative z-score indicate about a data point?
- How do you calculate the z-score from raw data?
- What is the relationship between the mean, standard deviation, and z-score?
- How do you interpret a z-score of 0?
- How can z-scores be used to compare data from different distributions?
Tip: A z-score of 2 or higher is typically considered unusual in many data sets, indicating that the value is significantly different from the mean.
