Table 4. Framingham data. Values of $t_{1}^{} (1)$ and $t_{2}^{}$ computed under the normal and mixture normal assumption. IND, RP, and HP represent individual response, random-pooling response, and homogeneous-pooling response, respectively. The numbers in parentheses in the rows for $t_{2}^{}$ are the p-values associated with $t_{2}^{}$ .
