put the numbers in order....very important
72,80,83,85,88,90,91,92,93,94
minimum (lowest number) = 72
Q1 = 83
Q2 (middle number) = (88 + 90) / 2 = 178/2 = 89
Q3 = 92
maximum (highest number) = 94
** this would have been answered a lot quicker if u would have posted in math section

The five-number summary for these data is:
Minimum = 72, Q1 = 83, median = 89, Q3 = 92, maximum = 94. Thus, option (a) is correct.
What is quartile?
The term quartile used in statistically as the value is divided into observation basis as quartile one, quartile 2, quartile 3.
Arranging Observations in the ascending order:
72,80,83,85,88,90,91,92,93,94
The minimum is 72 and the maximum is 94.
The calculation of Q1
Here, n=10
[tex]Q1 = (\frac{n+1}{4} )[/tex] th value of the observation
[tex]Q1 = (\frac{11}{4} )[/tex] th value of the observation
Q1 =(2.75) th value of the observation
Q1 =2nd observation +0.75[3rd-2nd]
Q1 =80+0.75[83-80]
Q1 =80+0.75(3)
Q1 =80+2.25
Q1 =82.25
The calculation of Q2:
Here, n=10
[tex]Q2=\frac{2(n+1)}{4}[/tex]th value of the observation
[tex]Q2 = (\dfrac{2.11}{4} )[/tex]th value of the observation
Q2 =(5.5)th value of the observation
Q2 =5th observation +0.5[6th-5th]
Q2 =88+0.5[90-88]
Q2 =88+0.5(2)
Q2 =88+1
Q2 =89
The calculation of Q3:
Here, n=10
Q3 =(3(n+1)/4)th value of the observation
[tex]Q3 = (\dfrac{3.11}{4} )[/tex]th value of the observation
Q3 =(8.25)th value of the observation
Q3 =8th observation +0.25[9th-8th]
Q3 =92+0.25[93-92]
Q3 =92+0.25(1)
Q3 =92+0.25
Q3 =92.25
Therefore, option (a) is correct.
