Question

For a particular known population, μ = 7.03 and σ² = 9.45. A researcher conducts a study in which 32 participants are given an experimental procedure. When testing the hypothesis that the population these 32 participants represent is different from the known population, the comparison distribution’s variance would be __________.

Answer 1

$\mu$ = Population Mean = 7.03

$\sigma$ = Population SD =

9.45 3.0741

n =Sample Size = 32

So,

Standard Error (SE) is given by:

3.0741 - 0.5434 /32 SE=

So,

the comparison distribution's variance is given by:

0.543420.2953

So,

Answer is:

0.2952
