In a survey of 3005 adults, it was found that 81% used at least one prescription medication. Construct a 90% confidence interval estimate of the percentage of adults who use at least one prescription medication

(n^3 - n)

= n(n-1)(n+1)

since it is divisible by 3 and 2 ,because it is a multiple 3 consecutive number

if, n-1 is odd then n+1 is also odd, then it is a multiple of 9

but if, n-1 is even then n+1 is also even, then it is a multiple of 4

so, largest multiple = max(9*2, 4*3) = max(18, 12) = 18

answer: about 22.67
