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:
Homework Answers
In s20 there are total 20
elements in which difference between two consecutive number is
50.

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

For n = 20, simulate a random
sample of size n from N(µ, 2 2 ), where µ = 1. Note that we just
use µ = 1 to generate the random sample. In the problem below, µ is
an unknown parameter. Plot in different figures: (a) the likelihood
function of µ, (b) the log likelihood function of µ. Mark in both
