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.
180-70-30=80 The answer is 80 The two triangles are the same. Corresponding angles of congruent triangles are equal. A triangle's three angles add up to 180 degrees.
