Question 1: Which minimum percentage is considered to be a large effect size? (answer as a decimal)

Question 2: Which minimum percentage is considered to be the ideal power you might obtain in a given study? (answer as a decimal)

Question 3: If statistical power for a given research study is .40, one can say that: "Assuming the researcher's prediction is correct, the researcher has a __________ chance of attaining statistically significant results."(answer as a percentage without the sign, e.g. 20, not 20%)

Question 4: For a known population that is normally distributed, M = 122 and SD = 8.What is the estimated effect size of a sample given an experimental procedure has a mean of 100?

In the experiment above, what would the effect size be if the experimental procedure has a mean of 120?

In the experiment above, which of the two effect sizes would be considered large? (re-enter the correct value)

Question 5: You plan on a study in which you think you may be able to raise people's I.Q by 5 points.We know that the population I.Q is normally distributed with a mean of 100 and SD of 16.What estimated effect size do you predict in your experiment?(answer as a decimal, round off to 2 places)

Question 6: In thinking about a possible experiment, you estimate, based on previous research in the subject, that 76% of population 1 will overlap with population 2's tail beyond the cutoff.How much power do you have? (answer as a decimal)
