The owner of an amusement park wants to find out which ride was the favorite among the park’s visitors on a given Saturday. On that day, there were 5,500 visitors. Help the manager choose which sample size is best. Arrange the samples starting with the greatest variation from the expected value and ending with the least variation. sample A: a sample of 10 people sample C: a sample of 90 people sample B: a sample of 55 people sample D: a sample of 200 people
what do you think it is?
I don't really know...
That's why I'm asking, so someone could help me figure it out. Math isn't my best subject...
ok what answer choices can u take out?
Well, the question is asking me to sort them.
Hey there!
Arrange the samples starting with the greatest variation from the expected value and ending with the least variation. Is what the question is asking.

We're doing a survey to find out what the best ride was at an amusement park If I survey only ONE person, and he tells me his favorite ride. Will that give me a good idea of what the favorite ride was for all the 5500 people who came to the amusement park?
Umm, yes.
Wait no.
Are you sure? Let me use a different example I'm asking everyone their favorite color. Your favorite color is, let's say blue. But everyone in your family loves green. If I only ask you, and you tell me blue.
Exactly!
Because that was only one person out of all of 5,500 visitors.
It's not going to be very helpful if we only ask one person. You would say that it's not a very good sample
Exactly! You're on the right track now
So we want to have a larger sample so that way our survey is MORE accurate
Yeah, ok I get it!
So does that mean it should be from greatest to least sense I should ask more visitors instead of less?
Like, Sample D 200 Sample C 90 Sample B 55 Sample A 10
The larger the sample size is the lower the variance is
So since they want us to order it from greatest variation to least variation so we have to go from least to greatest in terms of sample size
Oh! Ok thank you so much for your help!
I'm glad I could be of help!!
Have a great day! Bye!
You too!
