Question

The following table contains the reaction times for 5 different panel configurations for the emergency system and 20 operators responding to a particular emergency situation. The quality of a configuration panel can be measured by the mean reaction time and its standard deviation. Calculate the mean and standard deviation of the reaction time for each of the 10 panels. Which panel configuration would you recommend to minimize the risk of a nuclear accident caused by human error? Provide brief explanation of your answer referring to the numerical summaries.
