To produce a systematic sample if N = 1000 and n = 20,one could use the code below:

pickone <- sample(1:50, 1) # pick one at random from 1 to 50
s20 <- seq(from = pickone, to = 1000, by = 50)

The number of elements of s20 is:

    Let’s supposed that we want to choose a random sample of library books. There are four ways we can choose the random sample. Based on descriptions given below, label each as either simple random, stratified random, cluster random, or systematic random .a.The library books are storedon bookshelves. We number each bookshelf and use a random number generator to pick some bookshelves. All the books on the shelves that are picked will make up our random sample .b.We first organized the...

    Write a java code to do the following: 1- constant number for 1000 number that is the size of the array 2- sample size will be 50 3- so i want the program to get a random number for example. 1000/50 = 20 The random will start to see from 1 to 21 then to 41, 61, 91 and so on The 20 is the gap between the numbers. All the number should be consistent please
