Based on information about computer damage due to: 20% carelessness of the operator, 40% fluctuations in electricity voltage, 15% virus and 25% due to high room temperature. To test the validity of the information, samples were taken from 150 damaged computers and it turned out that there were 30 damaged units due to operator carelessness, 55 units due to voltage fluctuations, 20 due to viruses and the rest were damaged due to the high temperature of the room. By using the significance level = 0.05, can the results of the observations justify the information above?
