THE NEXT QUESTIONS ARE BASED ON THE FOLLOWING INFORMATION:
Let X1,X2,X3,and X4 be a random sample of observations from a population with mean μ and variance σ2.Consider the following two point estimators of μ:
1 = 0.10 X1 + 0.40 X2 + 0.40 X3 + 0.10 X4 and
2 = 0.20 X1 + 0.30 X2 + 0.30 X3 + 0.20 X4
-What is the relative efficiency of 1 with respect to
2?
Unconditioned Stimulus
A stimulus that naturally and automatically triggers a reflexive response without the need for prior learning.
Conditioned Stimulus
A previously neutral stimulus that, after being associated with an unconditioned stimulus, elicits a conditioned response in classical conditioning.
Unconditioned Response
An automatic, natural reaction to a stimulus that occurs without prior conditioning or learning.
Conditioned Response
A conditioned response is a learned reaction to a previously neutral stimulus that has become associated with an unconditioned stimulus through conditioning.
