Explanation / Answer

1. Which of the following would produce a standard error of 2 points?

formula of SE = thetha / srqt(n)

SE = 10 / srqt(25) = 2

so the answer is

A. N=25 scores from a population with theta=10

2. Which of the following samples would have the smallest standard error?

a) 10 / srqt(25) = 2

b) 50 / srqt(25) = 10

c) 20 / srqt(100) = 2

d) 10 / srqt(100) = 1

answer D. N=100 scores from a population with theta=10

3)

SE = 20 / srqt(25) = 4 points

Answer = 4 points
