(a) Min = _______
We know that the five-number summary of the data gives the following thing as below:
Min_value,1st_quartile, Median, 3rd_quartile, Max_Value
2.5.15) Let us assume the data can be written as X: 3,8,8,6,2,9,8,7,9,6,9,5,2,6,2,9,8,7,7,9
To find the five-number summary, we have to arrange data in ascending order as below:
X1: 2 2 2 3 5 6 6 6 7 7 7 8 8 8 8 9 9 9 9 9, total no. of observation n=20, From the above X1,
Min_value=2, 1st quartile is n/4 i.e. 20/4=5th position number in X1 i.e.5, 3rd quartile is 3n/4 i.e. 3*20/4=15th position number in X1 i.e. 8, Median is n/2 i.e.20/2=10 position number in X1 is 7, Max_value is 9
Hence, five-number summary of X is obtained as, 2, 5, 7, 8, 9. Min_vaue is 2
2.5.17) Let us assume the data can be written as Y: 3,8,8,4,2,9,8,7,9,6,9,3,1,6,2,9,8,7,7,9
To find the five-number summary, we have to arrange data in ascending order as below:
X1: 1,2,2,3,3,4,6,6,7,7,7,8,8,8,8,9,9,9,9,9, total no. of observation n=20, From the above Z1
Min_value=1, 1st quartile is n/4 i.e. 20/4=5th position number in Z1 i.e.3, 3rd quartile is 3n/4 i.e. 3*20/4=15th position number in Z1 i.e. 8, Median is n/2 i.e.20/2=10 position number in Z1 is 7, Max_value is 9
Hence, five-number summary of Z is obtained as, 1, 3, 7, 8, 9. Min_vakue is 1
Box_plot in above two cases is given below:

A modified box-and-whisker plot is a box-and-whisker plot that uses symbols to identify outliers. The horizontal line of a modified box-and-whisker plot extends as far as the minimum data entry that is not an outlier and the maximum data entry that is not an outlier. (a) Identify any outliers and (b) draw a modified box-and-whisker plot that represents the data set. 11,2,8,13,8,13,10,10,12,14,11,11,24,16,10 (a) Identify any outliers. Select the correct choice below and, if necessary, fill in the answer box to...
