Using concepts of <u>sample and population</u>, it is found that the sample variance is representative of 362 and 5530 customers ages, option D.
------------------------
In sampling, the <u>information is taken from a sample</u>, and is used to <u>estimate it for the whole population</u>.
- In this problem, we have a sample of 362 and a population of 5530 customers.
- The sample variance
is calculated from the sample, and used as an estimate for the population variance. Thus, it can be said that it represents both 362 and 5530 customers, and the correct option is D.

Answer:
The area of the four curved surfaces is the area of one circle with a radius of 4 cm
Area = PI * radius^2
Area = PI * 4 ^ 2
Area = PI * 16 = 50.26548245744 sq cm
Area of entire square = 8 * 8 = 64 sq cm
Area of yellow region = 64 - 50.265 sq cm =
= 13.735 = 13.7 sq cm (rounded to nearest tenth)
