Two school classes performed an experiment to determine the correct volume of a chemical solution. Their results, in millilitres, were presented as five-number summaries as follows. Class A: Min = 22.5, Q. = 23.5, median = 26.5, Q3 = 28.0 and max = 28.5 Class B: Min = 24.5, Q. = 25.0, median = 26.5, Q3 = 27.0 and max = 28.0 (a) Construct a parallel box-and-whisker plot of the above data.​
