What is an example of sample?
A sample is a small part of something that's shown to you to help define the full product.
How many integers between 1 to 25 would you expect to appear in a sample of 80 trials?
A sample of 5 integers selected is shown. Does this sample represent the general rule for picking an integer from 1 to 25 in the population of integers from 1 to 1,000? Explain.
How many different ways can you arrange the letters in number?
Assume you have 6 spots shown below: _ _ _ _ _ _ In the first spot, you have 6 letters to choose from. In the second spot, you have 5 letters to choose from because you already used one. Similarly, in the remaining spots, you will have 4, 3, 2, and 1 letters to choose from. So you have 6 choices * 5 choices * 4 choices * 3 choices * 2 choices * 1 choice = 720 possibilities
Can standard deviation be zero?
Yes, but only in the case where all numbers in your sample are the same. If you attempt to use a zero standard deviation in most statistical analyses, you will get an error message. Your sample has shown no variation so no inferences can be made to the general population.
What are the same throughout one sample would be similar to another sample?
Please look at your question. It is incomplete. It refers to a sample that is not shown. Finally, separate samples can range from identical to totally different - that's what sampling is usually about; finding how things relate over time/distance/temperature/season/mood/etc.,etc.,etc. Beano GB
