BJ makes a thermometers. The thermometers read in degree Celsius, are able to measure temperatures to a level of precision of two decimal places, Each hour, BJ tests randomly selected thermometers in a solution that is known to be at a temperature of 3 degree Celsius. use the following data to create and interpret an x-bar and R chart based on the desired thermometer reading of 3 degree Celcius ,interpret the result of your plotted averages and ranges
