Of those women who are diagnosed to have early-stage breast cancer, one-third eventually die of the disease. Suppose a screening program for the early detection of breast cancer was started in order to increase the survival rate p of those diagnosed to have the disease. A random sample of 200 women was selected from among those who were screened by the program and who were diagnosed to have the disease. Let x represent the number of those in the sample who survive the disease. USE SALT (a) If you wish to determine whether the community screening program has been effective, state the alternative hypothesis that should be tested. OH₂: P = ² O H₂: P > ² OH ₁: P OH₁; P< (b) State the null hypothesis. OH₂³ P = O Ho: P > ⒸH: P = ²/ OH:P < (c) If 170 women in the sample of 200 survive the disease, can you conclude that the community screening program was effective? Test using a = 0.05. Find the test statistic and the rejection region. (Round your answers to two decimal places. If the test is one-tailed, enter NONE for the unused region.) test statistic rejection region ܕ ܐ Z <
