Hey, please do only cluster sampling. I do not understand it. Just give me the 25...
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...
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 rating! 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...
identify the 25 correct statements in the set below identify 25 correct statements Please identify the 25 correct statements in the set below: Discovery analytics focuses on the question "Why did it happen?" Predicting a presidential candidate's percentage of the statewide vote from a sample of 800 voters would be an example of inferential statistics. This year, Oxnard University produced two football All-Americans. This is an example of continuous data. Sturges' Rule is merely a suggestion, not an ironclad requirement....
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...
PART F PART i In 1955, Life Magazine reported that a 25-year-old mother of three worked, on average, an 80 hour week. Recently, many groups have been studying whether or not the women's movement has, in fact, resulted in an increase in the average work week for women (combining employment and at-home work). Suppose a study was done to determine if the mean work week has increased. 68 women were surveyed with the following results. The sample mean was 83;...
This is JAVA programing problem. Please give me all necessary screenshot and comments. (I use Eclipse) Thanks Write a program that implements the FIFO, LRU, and Optimal page replacement algorithms presented in chapter 8 of your text. First generate a random page-reference string (this should be 20 entries long) where page numbers range from 0 to 9. Apply the random page-reference string to each algorithm, and record the number of page faults incurred by each algorithm. Implement the replacement algorithms...
Part B: Sampling and Random Variable You already have ten marked pennies (ones with numbers from Part A) and 15 unmarked pennies. Thought experiment: Throw them all in a jar and shake. Without looking, pull three out and record how many of them are marked (have a number). You will get 0, 1, 2, or 3 marked coins. How many different samples of 3 pennies out of 25 can you get? (Order doesn’t matter.) Answer: 2,300 Show why 2,300 is...
Please help ASAP please. Let X represent the full height of a certain species of tree. Assume that X has a normal probability distribution with mean 219.5 ft and standard deviation 62.5 ft You intend to measure a random sample of n 187 trees. The bell curve below represents the distibution of these sample means. The scale on the horizontal axis is the standard error of the sampling distribution Complete the indicated boxes, correct to two decimal places Points possible:...
Answer the following questions showing all work. Full credit will not be given to answers without work shown. If you use Minitab Express or StatKey include the appropriate output (copy + paste). If you do hand calculations show your work using the Word equation editor. Clearly identify your final answers. Output without explanation will not receive full credit and answers with no output or explanation will not receive full credit. Round all answers to 3 decimal places. If you have...
