A. Suppose that, for a particular type of cancer, chemotherapy provides a 5-year survival rate of 72%.

Among 20 patients diagnosed to have this form of cancer who are just starting the chemotherapy,

find the probability that at least 15 of them survive at 5-years or longer. Round answer to 3 significant

digits.

B. A home insurance company charges $2500 for the insurance policy. The policy only covers two

kinds of claims -- minor and large. Eight percent of homeowners will file a minor claim. When this

happens the insurance company pays out $10,000. Only 1% of the population will make a large

claim. When that happens the insurance company has to pay out $150,000. What is the expected

value of this policy to the insurance company?

C. The heights of National Basketball Association (NBA) players are normally distributed with a mean of

79” (6’7”) and a standard deviation of 3.89 inches. What heights delineate the middle 80% of NBA

players? Round your answer to the nearest inch.

Metastasis is responsible for about 90% of cancer associated deaths. The five year survival rate comparisons for metastatic and non-metastatic tumors in various tissues was presented in lecture 10. The prostate cancer survival rate for non-metastatic tumors is 100%, whereas for liver cancer it is 28%. Why do you think there is such a big difference in survival rates for these two cancer types when both are non-metastatic tumors? (5 points)

Part 1 Binomial Distribution [Mark 20%/cancer type, 40% total mark] Five year survival chance from any cancer depends on many factors like availability of treatment options, expertise of attending medical team and more. Five year survival rate is also an important measure and it is used by medical practitioners to report prognosis to patients and family. We will be analyzing five year survival rate of two types of cancer, very aggressive and very treatable cancer and to have comparative analysis...
