Using sampling concepts, the population and the sample are given as follows:
d. population: 6,000 batches of 100 cards sample: every 100th batch.
<h3>What is sampling?</h3>
It is a common statistics practice, when we want to study something from a population, we find a sample of this population, which is a <u>group containing elements of a population</u>. A sample has to be representative of the population, that is, it has to involve all segments of the population.
For example:
I want to estimate the proportion of New York state residents who are Buffalo Bills fans. So I ask, lets say, 1000 randomly selected New York state residents whether they are Buffalo Bills fans, and then:
- The population is: All New York State residents.
- The sample is the 1000 randomly selected New York state residents.
Hence, in the situation described the population is the 6,000 batches of 100 cards, while the sample is every 100th batch, hence option d is correct.

Answer:
The correct answer is:
0.01$ (c)
Step-by-step explanation:
Standard deviation is a measure of how spread out numbers are from the mean value. The formula for standard deviation is given by:
Variance is a measure of the squared differences from the mean.
Variance is simply the square of the standard deviation. It is mathematically shown as:
Now in our example,
Stabnard deviation = $0.10
Variance = (standard deviation)²
Variance = (0.10)²
Variance = $0.01
Answer:
The volume of a cube with side length 2 is 8.
Step-by-step explanation:
The argument of the function is the side length. In v(2), the argument is 2, so the side length of the cube of interest is 2 units.
The value of the function is the volume of the cube. The value of v(2) is 8, so that is the volume of the cube whose side length is 2.
Answer:
Crew: 32
Marty: 48
Blakely: 24
Step-by-step explanation:
I mainly just used guess and check. Crew is 32 years old. So, let's find Marty's age.
32 × 1. 5 = 48
Marty is 48. Now, let's find Blakely's age.
32 × 0.75 = 24
Add all the ages together.
32 + 48 + 24 = 104
Hope that helps.
