Answer:
The speed of 65 mph is an outlier in the distribution of the player's serve speeds
Step-by-step explanation:
We are given the following information in the question:
Mean, μ = 100 mph
Standard Deviation, σ = 10 mph
Formula:
Outlier on basis of z-score:
- Any z-score greater than 3 or less than -3 is considered to be an outlier.
- This rule of thumb is based on the empirical rule.
Calculation of z-score:
![x = 65\Rightarrow z = \dfrac{65-100}{10} = -3.5\\\\x = 110\Rightarrow z = \dfrac{110-100}{10} = 1\\\\x = 120\Rightarrow z = \dfrac{120-100}{10} = 2](https://tex.z-dn.net/?f=x%20%3D%2065%5CRightarrow%20z%20%3D%20%5Cdfrac%7B65-100%7D%7B10%7D%20%3D%20-3.5%5C%5C%5C%5Cx%20%3D%20110%5CRightarrow%20z%20%3D%20%5Cdfrac%7B110-100%7D%7B10%7D%20%3D%201%5C%5C%5C%5Cx%20%3D%20120%5CRightarrow%20z%20%3D%20%5Cdfrac%7B120-100%7D%7B10%7D%20%3D%202)
Thus, the speed of 65 mph is an outlier in the distribution of the player's serve speeds as the corresponding z-score is less than -3.
