Answer:
the probability that an individual, selected at random, will score below the mean on any normally distributed characteristic is just about 0.5.
Step-by-step explanation:
This probability in normal distribution corresponds to z-score of 0. Using normal distribution tables.
P(z < 0) = 1 - P(z ≥ 0) = 1 - 0.5 = 0.5
Which is very logical, to score below the mean on a normal distribution, the probability is just less than 0.5.

<h3>Width of rectangle = 7 cm</h3>
<h3>because ∵ width of rectangle is equal to the radius of each semicircle.</h3>
<h3>therefore ∴ radius of each semicircle (r) = 7 cm.</h3>
<h3>therefore ∴ Diameter of each semicircle = 14 cm</h3>
<h3>therefore ∴ Length of rectangle = 3 x 14 = 42 cm.</h3>
