Hey, please do only cluster sampling. I do not understand it. Just give me the 25...
Let's say I am interested in creating a sampling distribution with 25 students per sample to calculate the average number of credits PCC students are taking this term. In your own words, describe how we would create a histogram to represent a sampling distribution 25 observations per sample. For full credit, make sure your solution distinguishes your answer from a population distribution, and a sampling distribution of proportions.
Need help with 5 & 6 please

Central Limit Theorem for Means/Calculator Understand sampling distributions and the Central Limit Theorem for Means Question A head librarian for a large city is looking at the overdue fees per user system wide to determine if the library should extend its lending period. The average library user has $19.67 in fees, with a standard deviation of $7.02. The data is normally distributed and a sample of 72 library users is selected at random from the population. Select the expected mean...

please do all parts and be neat. i will give good

It is estimated that the average test score for a statistics exam will be u = 70, with a variance of o2 = 12. In a random sample of 8 students, the test scores are 65, 73, 74, 68, 70, 74, 69, 71, giving us the sample statistics i = 70.5 and s? = 10. Assume a normal distribution of scores. Answer the following questions to determine if...
I want to know how to do this assignment!!! Help me please~ The first part of your program should do the following: • Ask the user type of test they took. o (ACT or SAT) • If they said ACT then ask them their score o If their ACT score was between 0 and 7 say "Needs Work" o If their ACT score was between 10 and 20 say "Acceptable" o If they ACT score was above 20 say "Above...

Given X, and x, distributions that are normal or approximately normal with unknown o, and on, the value of t corresponding to X, - X, has a distribution that is approximated by a Student's t distribution. We use the convention that the degrees of freedom is approximately the smaller of n - 1 and n, - 1. However, a more accurate estimate for the appropriate degrees of freedom is given by Satterthwaite's formula: 2 2 xn2 522 +$22) d.f. z...
