Extracted text: 5. Assume the below life table was constructed from following individuals who were diagnosed with a słów-progressing form of prostate cancer and decided not to receive treatment of any form. Calculate the survival probability at year 2 using the Kaplan-Meir approach and interpret the results. Number of Number Survival Time in Years Number at Risk, Nt Deaths, Dt Censored, C Probability 20 1 1 20 3 -2 17 1 16 2 1 A) The probability of surviving 2 years after being diagnosed with a slow-progressing form of prostate cáncer is .85. B) The probability of surviving 2 years after being diagnosed with a slow-progressing form of prostate cancer is .85 for the individuals being followed in this study. 7( CYThe probability of surviving 2 years after being diagnosed with a slow-progressing form of prostate eancer is .85 for individuals who decided against all forms of treatment. * D) The probability of surviving 2 years after being diagnosed with a slow-progressing form of prostate cancer is .85 for the individuals being followed in this study and for individuals who decided against all forms of treatment.
