Solution
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
