1. Determine the appropriate sample size using G*power for a study that will employ an independent sample t-test, level of significance (alpha)= 0.05, power =0.80, and using the three levels of effect size

a) for a small effect size, use 0.20

b) for medium effect size, use 0.50

c) for a large effect size, use 0.80

2.) Which of the obtained values would be recommend? Explain why

3.) Why is it important that researchers determine the appropriate sample size with consideration of the level of significance, effect size, and power?
