In a study of 200 auto accident claims, it is found that claims are submitted t months after the accident occurs for t 0,1,2,.. and there is no withdrawal observation. $(t) is determined by the product-limit method, and its variance is estimated by Greenwood's formula. Find thee number of claims submitted at time t = 10, given the following value $(8) = 0,22 $(9) = 0,16 Est.Var[$(9)] = 0,00672 Est.Var[$(10)] [$(10)]* %3D = 0,04045
