The histogram below summarizes the survival times (in years)
from a study of a standard treatment for patients with metastatic
breast cancer. Use the histogram & the summary statistics
to answer the questions below:
The distribution of survival times is Select an
answer right-skewed bimodal uniform left-skewed normal . 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 Chebyshev's Rule the
Empirical Rule to this distribution, we estimate
that Select an answer 99.7% 75% or more 90% or
more 95% 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.
