A. Least value = 15

Greatest value = 30

B. The median on this box plot is 21. This means 21 is the middle-most value for the data. If all the values were lined up, 21 is center.

C. The lower quartile is 17.5 and the upper quartile is 27.5. These are the middle between the median and their respective end- least or greatest value.

D. 27.5 - 17.5 = 10

< coa = 150 ( given)

as ba and bc are tangents

so oc and oa is perpendicular to cb and ab respectively because in circle normal passes through centre

so in quadrilateral oabc

< coa + < oab + < ocb + < abc = 360

150 +90+90 + < abc = 360

330 + < abc = 360

< abc = 360 -330 = 30

so < abc = 30
