Question 5 1 pts A quality control lab has just purchased a new analytical instrument to replace the old one that has served for more than 10 years. Daily operation of the old instrument include running a sample of the same batch for 10 years as quality assurance measure. The old method yielded over all these years an average value of 10.5 ppm with a standard deviation of 0.2 ppm. The new instrument has been tested for a week and the first results are shown below 10.0 ppm 10.4 ppm 10.2 ppm 10.8 ppm 10.1 ppm 10.5 ppm 10.1 ppm What is the range of the data? 0.5 0.7 0.4 O 0.8

Explanation / Answer

range of a set of data = difference between the highest and lowest values in the set.

Here in this data set, highest value is 10.8 ppm and lowest value is 10.0 ppm.

so

range of data = 10.8 - 10.0 = 0.8 (answer)
