QUESTION 12 You are interested in seeing whether emotions impact decision making. You have three groups--a happy group, a sad group, and a neutral group. For the happy group there are 5 participants and the mean risky decision making score 5.0 with a standard deviation of 0.7. For the sad group there are 5 participants and the mean risky decision making score 5.4 with a standard deviation of 1.1. For the neutral group there are 5 participants and the mean risky decision making score 5.8 with a standard deviation of 2.8. The sum of squares between samples is equal to 1.6. The sum of squares within samples is equal to 38.0. You calculated the f-ratio above. The corresponding p-value for the f-ratio you calculated is p = 0.78. Is this finding significant? O No, the finding is not statistically significant because the p-value is smaller than .05. Yes, the finding is not statistically significant because the p-value is greater than .05. Yes, the finding is not statistically significant because the p-value is smaller than .05. O No, the finding is not statistically significant because the p-value is greater than .05.

QUESTION 12
You are interested in seeing whether emotions impact decision making. You have three groups--a happy group, a sad group, and a
neutral group. For the happy group there are 5 participants and the mean risky decision making score 5.0 with a standard deviation
of 0.7. For the sad group there are 5 participants and the mean risky decision making score 5.4 with a standard deviation of 1.1. For
the neutral group there are 5 participants and the mean risky decision making score 5.8 with a standard deviation of 2.8.
The sum of squares between samples is equal to 1.6. The sum of squares within samples is equal to 38.0. You calculated the f-ratio
above. The corresponding p-value for the f-ratio you calculated is p = 0.78. Is this finding significant?
O No, the finding is not statistically significant because the p-value is smaller than .05.
OYes, the finding is not statistically significant because the p-value is greater than .05.
O Yes, the finding is not statistically significant because the p-value is smaller than .05.
O No, the finding is not statistically significant because the p-value is greater than .05.
