Ratios
A ratio is a comparison between two numbers of the same kind. It represents how many times one number contains another. It also represents how small or large one number is compared to the other.
Trigonometric Ratios

1. The number of claims is modelled by a NB2(n, p) (the number of fail- ures before the nth success with probability p of success). The sample x = (x1, x2,,XN) with N = 100 returns N N xj = 754, Σε = 70425. j=1 Estimate the parameters n and p using the point estimates. [5 Marks]
