You find an average of 89.3 with a standard deviation of 9 for the sample. Test the null hypothesis that you and your friends are just a random selection from the state population (μ = 84.7), using alpha = .05 (two-tailed). a. H0: μ =
b. Sample Mean: X̅ =
c. Sample Standard Deviation: sX =
d. Standard Error: sX̅ =
e. tcv = ; t( ) = ; 2-tail: p =
f. What is the effect size? d =
g. Provides Evidence that you and your friends are not a random selection from the state ☐No Evidence that you and your friends are not a random selection from the state
h. What conclusions can you draw from the results above?
