A gravimetric analysis was preformed on an unknown chloride sample in the laboratory to try and determine the identity of the solid. if the results of the experiment were 32.52%, 32.14%, 32.61 and 41.29 what is the mean, standard deviation and relative standard deviation of these experiments? finally, can any of these results be discarded and if so why?

In a laboratory setting, one way to ensure accuracy is to use repeated measurements when conducting an experiment. Suppose that a lab assistant was given 10 experiments to conduct. After each experiment, she had to measure the weight of the result on two different scales, scale A and scale B. The mean difference of the weights of the 10 experimental results was 1.87 grams with a standard deviation of 1.33 grams (scale A – scale B). It is suspected that...
