policv . 1.67 Does radeness really matter in the workplace? Studies have established that rudeness in the work ace can lead to retaliatory and counterproductive vior. However, there has been little research on how rude behaviors inluence a victim's task performance, such a study was conducted d the results published in the Academy of Management Journal (October 2007). Colle students enrolled in a management course were randomly assigned to one of two experimental conditions: rudeness condition (45 students) and control group (53 stu- dents). Hach student was asked to write down as many uses for a brick as possible in 5 minutes. Por those students in the rudeness condition, the facii- tator displayed rudeness by berating the students in general for being irresponsible and unprofessional due to a late-arriving confederate). No comments were made about the late-arriving confederate for students in the control group. The number of dif- ferent uses for a brick was recorded for each of the 98 students and the data suved in the RUDE file, shown below: Conduct a statistical analysis (at -.01) to determine if the true mean perfor- mance level for students in the rudeness condition is lower than the true mean performance level for students in the control group.

now we use
here we use t-test with null hypothesis H0:mean1=mean2 and alternate hypothesis H1:mean1>mean2
t=(mean1-mean2)/((sp*(1/n1 +1/n2)1/2) and sp2=((n1-1)s12+(n2-1)s22)/n and with df is n=n1+n2-2
since p-value is less than alpha=0.01, so we reject null hypothesis and conclude that rudeness mean is less than control group
