Question 20: A value of Us equal to 0 implies high practical significance. (1 Points) True FalseIf H1: H1 - Ho > 0 and a = .05, what should my sample size be to achieve power = .8 If I'm only interested in 8 = 4? 619 O 155 O 4 O 39Psychologist generally do not strive to have experiments with high power O True O FalseIf H1: H1 - Ho # 0 and a = .05, what effect size seems to interest me if I wish to achieve power = .95 with a sample size of 21? 0.6 O 0.8 0.5 O 0.1tion 6: nt) interested in 8 = .4?
