of those women who are diagnosed to have early stage breast cancer one third eventually die of the disease. suppose a screening program for 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.

3 O Hip * (c) If 169 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 Z rejection region Z Z State your conclusion and explain the practical conclusions from your test. O Ho is not rejected. There is insufficient evidence to indicate that p is greater than -. The screening program does not seem to increase the survival rate. O Ho is not rejected. There is sufficient evidence to indicate that p is greater than . The screening program seems to increase the survival rate. O Ho is rejected. There is insufficient evidence to indicate that p is greater than . The screening program does not seem to increase the survival rate. O Ho is rejected. There is sufficient evidence to indicate that p is greater than -. The screening program seems to increase the survival rate. (d) Find the p-value for the test. (Round your answer to four decimal places.) p-value = Interpret the p-value. Since the p-value is greater than 0.10, the results are not statistically significant. Since the p-value is between 0.05 and 0.10, the results are tending toward statistical significance. Since the p-value is between 0.01 and 0.05, the results are statistically significant. O Since the p-value is less than 0.01, the results are highly significant
