The distribution of survival times is Select an answer. The average survival time for this sample of women undergoing the standard treatment is years, while 50% of the women in the sample had a survival time of years or longer. The minimum survival time was years, while the maximum was years. According to the IQR, % of the women in the sample survived between and years when given this treatment. Applying Select an answer to this distribution, we estimate that Select an answer of women with metastatic breast cancer will survive between and years (3 standard deviations from the mean).
Note: Round any values to 4 decimal places when answering. Make sure the limits of the interval calculated are legitimate values for the variable being described.
