In a Cartesian coordinate plane, there are 4 quadrants. The axes that divide the four quadrants are called the y and x-axis. The positive x-axis has a value of 0° or any value divisible by 360°. So we don't have any problem with the x axis since both situation given are at 0°. However, the positive y-axis is at the top while the negative y-axis is at the bottom. A negative angle means the rotation is clockwise. A positive angle means that the rotations is counter-clockwise. Thus, the answer is false.

Answer:

b) LeBron is relatively taller because he has a larger z-score.

Step-by-step explanation:

Z-score:

In a set with mean $\mu$ and standard deviation $\sigma$ , the z-score of a measure X is given by:

$Z = \frac{X - \mu}{\sigma}$

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the p-value, we get the probability that the value of the measure is greater than X.

LeBron James:

Height of 81 inches, while the average 30- to 39-year old man is 69.5 inches tall, with a standard deviation of 2.7 inches, which means that we have to find Z when $X = 81, \mu = 69.5, \sigma = 2.7$

$Z = \frac{X - \mu}{\sigma}$

$Z = \frac{81 - 69.5}{2.7}$

$Z = 4.26$

Candace Parker:

Height of 76 inches, while the average 30- to 39-year old woman is 64.2 inches tall, with a standard deviation of 3.2 inches. This means that we have to find Z when $X = 76, \mu = 64.2, \sigma = 3.2$
