                                             Diesease                No-Diesease                Tt

Actual              Diesease           225                           75                         300

No-Diesease         25                175                            200

                                                  250                           250                       500

so finding the predictive value positive of the test,

predictive negative value = (175 / (75+175) )

= 175 / 250

= 0.7

Therefore the predictive value positive of the test is 0.7
