1. In a large company, where employees frequently need to work in team projects, the difference in the team efficiency is examined, when employees work in teams through distance working (e.g. with virtual meetings) in relation to teamwork with physical presence. Data are collected from 46 employees that have worked in a team project through teleworking and 43 employees that have worked in a team with physical presence. Theemployees filled a questionnaire, where one question was "The teamwork was efficient",on a scale from 1-5, where 1=strongly disagree and 5=strongly agree. The mean score in this question for the team that had used teleworking was 2.74, with a standard deviation of 0.96, while for the team that had worked with physical presence the mean was 1.88, with a standard deviation of 0.92. Test if teamwork with distance meetings in this company appears to be more efficient, in relation to teamwork with physical presence. Use a 10% level of significance.
