a) If a man is 6 feet 3 inches tall, what is his z-score (to two decimal places)?
z =
b) If a woman is 5 feet 11 inches tall, what is her z-score (to two decimal places)?
z =
c) Who is relatively taller?

You can put this solution on YOUR website! **a) Z-score for the 6-foot-3-inch man:**
* **Convert height to inches:** 6 feet 3 inches = 75 inches
* **Calculate z-score:**
z = (x - μ) / σ
z = (75 - 69.3) / 2.68
z ≈ 2.14
**b) Z-score for the 5-foot-11-inch woman:**
* **Convert height to inches:** 5 feet 11 inches = 71 inches
* **Calculate z-score:**
z = (x - μ) / σ
z = (71 - 64.5) / 2.59
z ≈ 2.51
**c) Who is relatively taller?**
* The **woman** is relatively taller.
**Explanation:**
* A higher z-score indicates that the individual is further above the mean of their respective population.
* The woman's z-score of 2.51 is higher than the man's z-score of 2.14, meaning she is further above the average height for women than the man is above the average height for men.
