In descriptive statistics, the interquartile range<span> (</span>IQR<span>), also called the midspread or middle 50%, or technically H-spread, is a measure of statistical dispersion, being equal to the difference between 75th and 25th percentiles... ~ wikipedia
according to Wikipedia and some quick mental math the answer would be four
four is the difference between 14 and 18 which are respectively the 25th and 75th percentiles.</span><span />
Answer:
5)surface =2(lb*bh*hl)
=2(12*4+4*4+4*12)
=2(48+16+48)
=2(96+16)
=2*112
=224inc^2
6)surfacearea=2*pi*r(r+h)
=2*3.14*2(2+1)
=6.28*2*3
=6.28*6
=37.68m^2
(9+8+2)/(4+9+8+2)=19/23=82%
Therefore very likely
