In order to use the t distribution, you will first need to determine the degrees of freedom (df) for a = .05. The degrees of freedom (df) isThe critical value of t isYour sample of 16-year-old children with antisocial tendencies has an average score of 13.10 with a standard deviation of 2.85.Calculate the t statistic. To do this, you will first have to calculate the estimated standard error. The estimated standard error isThe t statistic is(Hint: For the most precise results, retain four significant figures from your calculation of thestandard error to calculate the t statistic.)The t statisticlie in the critical region. Therefore, youreject the null hypothesis.Based on the results of this test, thereenough evidence to conclude that children with antisocial tendencies have greaterdifficulty recognizing anger than do children without antisocial tendencies. Antisocial personality disorder (ASPD) is characterized by deceitfulness, reckless disregard for the well-being of others, a diminishedcapacity for remorse, superficial charm, thrill seeking, and poor behavioral control. ASPD is not normally diagnosed in children oradolescents, but antisocial tendencies can sometimes be recognized in childhood or early adolescence. James Blair and his colleagueshave studied the ability of children with antisocial tendencies to recognize facial expressions that depict sadness, happiness, anger,disgust, fear, and surprise. They have found that children with antisocial tendencies have selective impairments, with significantly moredifficulty recognizing fearful and sad expressions.Suppose you have a sample of 25 16-year-old children with antisocial tendencies and you are particularly interested in the emotion ofanger. The average 16-year-old has a score on the emotion recognition scale of 12.50. (The higher the score on this scale, the morestrongly an emotion has to be displayed to be correctly identified. Therefore, higher scores indicate greater difficulty recognizing theemotion). Assume that scores on the emotion recognition scale are normally distributed.You believe that children with antisocial tendencies will have a harder time recognizing the emotion of anger (in other words, they willhave higher scores on the emotion recognition test).

Here, The null hypothesis is H0: μ0=12.5 The alternative hypothesis is H1:μ0>12.5 Total number of…

Antisocial personality disorder (ASPD) is characterized by deceitfulness, reckless disregard for the well-being of others, a diminished capacity for remorse, superficial charm, thrill-seeking, and poor behavioral control. ASPD is not normally diagnosed in children or adolescents, but antisocial tendencies can sometimes be recognized in childhood or early adolescence. James Blair and his colleagues have studied the ability of children with antisocial tendencies to recognize facial expressions that depict sadness, happiness, anger, disgust, fear, and surprise. They have found that children with antisocial tendencies have selective impairments, with significantly more difficulty recognizing fearful and sad expressions. Suppose you have a sample of 40 12-year-old children with antisocial tendencies and you are particularly interested in the emotion of anger. The average 12-year-old has a score on the emotion recognition scale of 11.80. (The higher the score on this scale, the more strongly…

"Bullying," according to noted expert Dan Olweus, "poisons the educational environment and affects the learning of every child." Bullying and victimization are evident as early as preschool, with the problem peaking in middle school. Suppose you are interested in the emotional well-being of not only the victims but also bystanders, bullies, and those who bully but who are also victims (bully-victims). You decide to measure depression in a group of victims and a group of bully-victims using a 26-item, 3-point depression scale. Assume scores on the depression scale are normally distributed and that the variances of the depression scores are the same among victims and bully-victims. The group of 25 victims scored an average of 25.3 with a sample standard deviation of 9 on the depression scale. The group of 23 bully-victims scored an average of 20.5 with a sample standard deviation of 8 on the same scale. You do not have any presupposed assumptions about whether victims or bully-victims…
