Her sample space is also the list of local businesses.
Sampling is a technique used in statistics when researchers choose a representative subset of a larger population and utilize that subset to carry out a study. Probability sampling and non-probability sampling are the two main types of sampling. Selecting the group from whom you will actually gather data for your study is the process of sampling. If you wanted to examine the perspectives of students at your university, for instance, you could interview a sample of 100 students. With the help of sampling, you can test a statistical hypothesis on the features of a population.
The yellow pages are used by the researcher to do research on neighborhood companies. As a result, her sample space also includes a list of nearby companies.
Complete question: A researcher is conducting a study on local businesses. In order to create her sample, she uses the Yellowpages and a dice. She rolls the dice, and, depending on the number rolled, counts that many businesses down in the list to call. What is her sampling frame?
The list of local businesses in the Yellowpages.
All businesses within a
radius.
The list of local businesses in the newspaper.
All businesses in the state she is located in.
The list of registered businesses in her area.

Answer:
The probability of selecting the color of ball that you just selected(a red ball) is ![P(r) = \frac{2}{10}](https://tex.z-dn.net/?f=P%28r%29%20%3D%20%20%5Cfrac%7B2%7D%7B10%7D)
Step-by-step explanation:
From the question we are told that
The total number of colored balls is n = 10
The number of red balls is r = 2 red
The number of white ball is w = 4
The number of blue balls is b = 4
The number of balls to be selected is N = 2 balls
The cost of playing picking a ball is c = $10
The winnings is ![k = \$ P(A)](https://tex.z-dn.net/?f=k%20%3D%20%20%5C%24%20P%28A%29)
Here P(A) is the probability of obtaining the exact sequence of result and from the question it is P(A) = 0.10
Generally my price according to the question is
![k = \frac{0.10 }{10}](https://tex.z-dn.net/?f=k%20%3D%20%20%5Cfrac%7B0.10%20%7D%7B10%7D)
=> ![k = 0.01](https://tex.z-dn.net/?f=k%20%3D%20%200.01%20)
Let assume we selected a red ball
Generally the probability of selecting a red ball is mathematically represented as
![P(r) = \frac{2}{10}](https://tex.z-dn.net/?f=P%28r%29%20%3D%20%20%5Cfrac%7B2%7D%7B10%7D)
Answer:
No solution
Step-by-step explanation:
8+8-4 = 12
12+ n = 3n-2n
3n-2n
12+n3n-2n
subtract n on both sides
12=0n
This makes it no solution
Answer:
268 students are absent
Step-by-step explanation:
First, multiply 775 by (8/25) to get the number of students out from the virus (probably weren't wearing masks or 6 ft apart from each other). This gives you 248 students. You also know that an additional 20 students are out due to other reasons. Add 248 and 20 and you get a total of 268 absent students.
