ssume the obtained value of the appropriate statistic is t obt = -2.431, using α = 0.05, 2 tail, and t crit = +2.228 and -2.228, what do you conclude? a. retain null hypothesis, suggesting that violent TV show does not affect aggression. b. reject null hypothesis, suggesting that violent TV show affects aggression.
A psychologist wants to know whether viewing more violent TV shows affects aggressive behavior. 12 children were chosen at random for an experiment and randomly allocated to one of two conditions. In condition 1, six kids were given an aggressive behavior test. The more aggressive the conduct, the higher the score. In condition 2, six children were given the identical test after watching two hours of tv shows. The following results were obtained.
| Condition 1 | 5 | 14 | 6 | 8 | 7 | 6 |
| Condition 2 | 12 | 14 | 14 | 8 | 15 | 9 |
Assume the obtained value of the appropriate statistic is t obt = -2.431, using α = 0.05, 2 tail, and t crit = +2.228 and -2.228, what do you conclude?
| a. |
retain null hypothesis, suggesting that violent TV show does not affect aggression. |
|
| b. |
reject null hypothesis, suggesting that violent TV show affects aggression. |
