The minimum value is % (Round to three decimal places as needed.) The maximum value is %. (Round to three decimal places as needed.) The median is |% (Round to three decimal places as needed.) Q1 = % (Round to three decimal places as needed.) Q3 = % (Round to three decimal places as needed.) b) Find appropriate measures of centre and spread for these data. To find any quartiles used in the answer, first split the sorted data at the median. Then find the median of each of these halves and use them as the quartiles. Which of the following
