1. What are two things you can do to decrease the sample size? (Hint: the three components that determine sample size are: standard deviation/variance, z-score, margin of error) Which of those three components is something you don't have control over?
2. There comes a point at which a bigger sample size just doesn't give much better precision. Around what sample size do you start seeing diminishing returns?
Homework Answers
answer..
1.
a.Utilize a superior measurable procedure, which can extricate more data out of the information
b.Utilize a combined test for example test a similar gathering twice (which viably slices your example measure down the middle)
We don't have power over standard deviation/difference

For the following scenarios, please tell me what the minimum sample size needed is, rounded up to the nearest integer (e.g., if your answer is 51.3, round it up to 52). Remember that you cannot survey a fraction of a person – it has to be a whole person. If you round down, then you won’t have the minimum amount of precision needed, so you must round up. For the z-scores, refer to table provided Confidence Level z-score 90% 1.65...

1. Explain the relationship between sample size and standard error. 2. You have a normal population with a u = 50 and o = 9. You obtain all possible random samples, each with n = 30, from this population and calculate each sample's mean. What will the average value of all the sample means be? a) 50 b) 5.56 c) 30.49 d) Cannot tell without more information 3. You are sampling from a distribution of scores that is positively skewed....

Please how could you paraphrase these 2 sentences: 1. One major positive for this study is that it is observational, so no possible errors can come from the experimenter interfering with the study. A limitation that stood out to me the most in this study would be the sample size only being 167, although it is a good thing to have a wide range of ages 8 to 17, only having 167 doesn't really provide the best results or a...

These are the hints:
Summary This week's lab is to create a simple multiplication table using nested loops and if statements. Prompt the user for the size of the multiplication table (from 2x2 to 10x10). Use a validation loop to display a warning if the number is less than 2 or greater than 10 and prompt the user to enter the data again until they enter a valid number Put a...

Card Game Simulation(in Python 3.8.1) The purpose of this assignment is to help you gain experience using while loops to solve problems. For this assignment, you will simulate a simplified card game that has some similarity to the game of 21. At the start of the program, the user will be asked to supply both the winning score (an integer from 1 thru 21) and the number of times to run the simulation (an integer from 100 to 100,000). To...
