A doctor is interested in the proportion of patients which live at least 5 years after being diagnosed with stage 4 breast cancer. He randomly selects 96 patients diagnosed with stage 4 breast cancer and follows them for 5 years. Suppose the true 5 year survival rate for stage 4 breast cancer is 25%.

How are the collection of all sample proportions of samples of size 96 distributed?

N(, )

What is the probability that fewer than 22% of the patients studied survived for at least 5 years?
- There is a chance that fewer than 22% of the patients studied survived for at least 5 years.

What is the probability that more than 33% of the patients studied survived for at least 5 years?
- There is a chance that more than 33% of the patients studied survived for at least 5 years.

What is the probability that between 22% and 33% of the patients studied survived for at least 5 years?
- There is a chance that between 22% and 33% of the patients studied survived for at least 5 years.
