Hello, My name is Walter. I'm taking a business statistics class this semester. I learned this week that any number that is 20 times greater than another number is considered to be infinite. So, say that we start with the number 9. 9*20=180 So, from this point of view, for example, a value of 180 is considered to be infinite when compared to 9. This would be used, say, in a population of 180, or more, which might as well be considered an infinite population when sampling 9 people out of a population of 180+. Or, in other words, the sampled population of 9 is too small of a group to represent the entire population. 20 times a number is infinite. That's all.
I'm afraid your business professor doesn't grok the meaning of infinity. I'd seek another teacher were I you.
This was from the textbook and infinity as a statistics term is different from the mathematical infinity.
Most people take classes to learn something. How would a person that doesn't know a subject know the information they are receiving is questionable? In this case, it's not but, if it was, that would be difficult. It's the same "logic" behind blaming people for getting connecting with bad therapists. They are chastised with "You need to pick the right therapist." Well, if a person needs therapy, they probably struggle with interpersonal relationships and boundaries. As above, they usually aren't in the position to know anything may be amiss. Sometimes it helps to try to other people's point of view. That can go a long way to helping one another. It doesn't always work but there usually isn't anything to lose by making the effort.
It's been 40 years since I took stats. But maybe this will help: https://www.statisticshowto.com/finite-set-infinite-statistics/
