The driver's reaction time in response to a particular potential traffic hazard is the time required from the point of initial detection of the hazard in one’s field of view to the time that vehicle control components are actuated (such as movement of one’s foot to the brake pedal). The following data represents the measurements of the driver’s reaction time in seconds for the male and female participants of the experiment: (a) Calculate the sample mean of the data. Calculate the sample variance of the data. Calculate the corresponding sample standard deviation. (b) Find the median and quartiles for the data. (c) Construct a box plot of the data. Find the interquartile range and determine the number of outliers. 0.50 0.49 0.45 0.54 0.44 0.49 0.51 0.48 0.51 0.53 0.51 0.63 0.69 0.76 0.76 0.85
