IncorrectQuestion 3 IfH0is true, then the probability of rejectingH0is limited by ____. Power 1-power alpha beta IncorrectQuestion 4 Exhibit 11-1 You are considering testing a new drug that is supposed to facilitate learning in mentally retarded children. Because there is relatively little known about the drug, you plan to use a nondirectional alternative hypothesis. Since your resources are limited, you can test only 15 subjects. The subjects will be run in a repeated measures design and the data will be analyzed with the sign test, usinga= 0.052 tail. Refer to Exhibit 11-1. If the drug has a moderate effect on learning such thatPreal= 0.70, what is the probability you will detect the effect when doing your experiment. 0.2968 0.0176 0.2969 0.0352 Question 5 You are considering testing a new drug that is supposed to facilitate learning in mentally retarded children. Because there is relatively little known about the drug, you plan to use a nondirectional alternative hypothesis. Since your resources are limited, you can test only 15 subjects. The subjects will be run in a repeated measures design and the data will be analyzed with the sign test, usinga= 0.052 tail. Refer to Exhibit 11-1. What is the probability of a Type II error? 0.7032 0.7031 0.9824 0.9648 Question 7 In the case ofN= 3,Preal= 0.90,a= 0.051 tail, using the sign test, the power is ____. 1.0000 0.1250 0.8750 0.0000 Question 9 IfN= 4,Preal= 0.80 in the direction predicted, anda= 0.051 tail, using the sign test, the power is ____. 0.9375 0.0000 1.0000 0.0625 IncorrectQuestion 10

If beta = 0.7500, what is the power of the experiment? 0.7500 0.5000 0.2500 1.0000 Question 11 Assume that you have conducted an experiment and the tail probability for the results you obtained was 0.0900 anda= 0.05. You can conclude ____. the independent variable has no effect the independent variable has a weak effect you were unable to detect an effect of the independent variable with your experiment the null hypothesis is false IncorrectQuestion 12 Truth demands that scientists set ____. alpha equal to 0.05 alpha equal to 0.01 alpha equal to 0.03 not necessarilya= 0.01 or 0.05 or 0.03, but use their best judgment Question 14 A real effect of the independent variable is defined as ____. all possible effects including no change in the dependent variable any effect that produces a change in the dependent variable an effect that produces an increase in the value of the dependent variable an effect showing no change in the dependent variable
