What is the difference between the sample average y and the population​ mean?

Mathematics

stepan [7]3 years ago

When a finite number of samples are drawn from a larger population, the sample mean of that sample, while usually close to the population mean, is not the same thing.  A population mean, on the other hand, is a description of pretty much ALL of whatever is being examined.

Example of population:  Everyone in the USA
Example of a sample:    One person, chosen at random, from each of the 50 states

A certain big company classifies its employees according to gender, age-group (6 categories) and employment type (10 categories)
elena-14-01-66 [18.8K]

We don’t know the number of employees remaining at the company.

We don’t know the total number of employees remaining at the company.

The classification consists of gender, division, and employment type.

It doesn’t matter what order those attributes come in. A person who is male, age group 6, and employment type 10 has the same classification as someone who is of employment type 6, male, and age group10.

Therefore since order does not matter it is a combination question.

Assuming only two genders are allowed (you didn’t say and some people think there are about 10 of them)

It is either 120 (2 times 6 times 10) or "None of the above" if you believe there are more than 2 genders.

2×6×10=120

Amanda is 25 years old. in 5 years she will be twice as old as simone how old i simone
Nadya [2.5K]
We could use Algebra for this question but it’s quite simile so won’t need it. If Amanda is 25, when we add on 5 years she’ll be 30. Now it says when she’s 30, she will be twice as old as Simone. Implying that Simone will be half of Amanda’s age. In this case 30/2 = 15. So Simone must be 15.
