The ascending order of the percentages obtained by John is 70, 76, 80, 82.

In the percentages, the least value is 70 and the greatest value is 82.

Middle quartile = Median of all the data

= 76 + 802 = 1562 = 78

Lower quartile = Median of lower half of the data

= 70 + 762 = 1462 = 73

Upper quartile = Median of upper half of the data

= 80 + 822 = 1622 = 81

So, plot (1) is the equivalent box-and-whisker plot of the data.

Median of the scores obtained by John = Middle quartile = 78

TJoseph, John, ascending order of tJoseph, John, number of coins collected by each student is 10, 16, 16, 18, 20.

In tJoseph, John, table, least value is 10 and tJoseph, John, greatest value is 20.

Middle quartile = median of tJoseph, John, entire data = 16

Lower quartile = median of lower half of tJoseph, John, data

Upper quartile = Median of upper half of tJoseph, John, data

Plot (1) is tJoseph, John, equivalent box-and-whisker plot for tJoseph, John, data.

Range of tJoseph, John, box-and-whisker plot

The number of customers who visited the super market each hour are 15, 10, 12, 9, 18, 5, 8, 9, 15, 10 and 11.

The ascending order of the above data set is: 5, 8, 9, 9, 10, 10, 11, 12, 15, 15,18.

The least value in the above list of data is 5 and the greatest value is 18.

Middle quartile = median of the data = 10.

Lower quartile = median of lower half of the data = 9.

Upper quartile = median of upper half of the data = 15.

So, among the plots, plot 4 is the equivalent box-and-whisker plot for the data.

The least value in the above list of data = 10 and the greatest value = 200.

Middle quartile = median of all the data = 80.

Lower quartile = median of lower half of the data = 10 + 402 = 502 = 25

Upper quartile = median of upper half of the data = 150 + 2002 = 3502 = 175

So, plot 3 is the equivalent box-and-whiskers plot for the data.

The number of passengers transported in 7 trips in a day are 50, 70, 60, 80, 40, 75, 50.

The ascending order of the above data set is 40, 50, 50, 60, 70, 75 and 80.

The least value in the above list is 40 and the greatest value is 80.

Middle quartile = median of the data = 60.

Lower quartile = median of lower half of the data = 50.

Upper quartile = median of upper half of the data = 75.

Plot (2) is the appropriate box-and-whisker plot of the data.

Median of the data = middle quartile of the plot = 60

From the table, the heights of mountains in the U.S are 200, 180, 175, 165, 160, 145 and 140.

The ascending order of the above data set is 140, 145, 160, 165, 175, 180, 200.

So, the least value in the data set is 140 and the greatest value is 200.

Middle quartile = median of the data = 165.

Lower quartile = median of lower half of the data = 145

Upper quartile = median of upper half of the data = 180

So, plot (1) is the appropriate box-and-whisker plot of the data.

Mean of the data = sum of the heights / number of heights given = [(140 + 145 + 160 + 165 + 175 + 180 + 200) / 7] x 100 = 166.43 x 100 = 16643 ft.

The ascending order of the number of viewers in the data is 10, 14, 16, 20 and 32.

The least value in the above list is 10 and the greatest value is 32.

Among the plots, plot (4) is the appropriate box-and-whisker plot for the data.

Mean number of T.V viewers = Sum of the viewers of all channels / Number of channels

The ascending order of the data is 2, 2, 3, 4, 5, 5, 7, 8, 9, 10 and 12.

The least value in the data set is 2 and the greatest value is 12.

So, Plot 3 is the appropriate box-and-whisker plot for the data set.

The ascending order of the above data set is 2, 3, 5, 6, 7, 8 and 10.

From the above data set, the least value is 2 and the greatest value is 10.

Among the four plots, plot (2) is the equivalent box-and-whisker plot of the data.

Range = greatest value - least value.

The ascending order of the above data set is: 8, 10, 11, 12, 13, 14, 15, 17, 17, 18, 18, 19, 19, 20, 20.

From the above list of data, least value = 8 and greatest value = 20.

The range of the data = 20 - 8 = 12

Middle quartile = median of all the data set = 17.

Lower quartile = median of lower half of the data set = 12.

Upper quartile = median of upper half of the data set = 19.

Among the four plots, plot (2) is the appropriate box-and-whisker plot of the data.
