Question 12 0.5 pts Data Set 8-2 Scores: 1, 2, 3, 4, 5 (This data is used in multiple questions in this quiz.) Refer to Data Set 8-2. For Ho: / = 4.00, the effect size index is O 0.63; O 0.57; O 1.41; O none of the other alternatives are correct.D Question 13 1 pts Some people claim that psychology is common sense. If this is true, then students who have not taken psychology courses should be able to predict the outcomes of experiments as well as psychology majors. If it is not, then nonpsychology students should perform worse than psychology students. Psychology students typically predict outcomes with m = 75% accuracy. To test whether there is any difference between psychology and non psychology students, a sample of 15 nonpsychology students were tested and they predicted with a x- 60% accuracy. The $x -2.696. What is the 95% confidence interval for nonpsychology students? (this data is used in another question on this exam) 54.22 and 65.78% 55.25 and 64.75 54.36 and 65.85% 69.22 and 80.78% Question 14 1 pts Some people claim that psychology is common sense.

To test whether there is any difference between psychology and non psychology students, a sample of 15 nonpsychology students were tested and they predicted with a Y= 60% accuracy. The $x - 2.696. Using the 95% confidence interval for nonpsychology students, what is your conclusion about their ability to predict the outcomes of experiments? (this data was used in another question on this quiz) O Cannot be determined Nonpsychology students performed the same as the Psychology students Nonpsychology students performed better than the psychology studentts O Nonpsychology students performed worse/less than the Psychology StudentsQuestion 15 0.5 pts What is the tcrit value(s) for a two tail test at the alpha level at .01 when 25 participants are tested? O +/- 2.064 0 +/-2.797 O cannot determine from the above Question 16 1 pts t test was conducted nd the tobt was a negative value. How do you compare the tobt to the tcrit? Negative only means that the population mean is greater than the sample mean so take the absolute value of t and compare with the tcrit O Negative means that you automatically reject the Null hypothesis and then write up the interpretations O There was something wrong with the calculation If it's a negative number then it is always considered less than the table valueQuestion 17 1 pts Suppose that you had constructed from a sample data a 99 percent confidence interval about the sample mean. This means that O You are 99% sure that the interval contains the population mean None are correct Both are correct O the population mean has .95 probability of being in the interval Question 18 0.5 pts t test was conducted and it was statistically significant at the p<.05. what possible error could you have made type ii error: rejecting the null when it is trye no if i didn any calculation hypothesis true o either possibledata set scores: data used in multiple questions this quiz. t value calculated using scores above were tested against ho: m="1.00" leads to conclusion that should be... rejected at .05 level for a two-tailed test and .01 retained. .001 question refer effect size index none of other alternatives are correct. pts tobt o. be fail reject>
