A cancer drug is produced in one kilogram batches, with an average of six batches produced every hour. Assume the waiting time until the next batch is exponentially distributed.

a) What is the probability the production process requires more than 15 minutes to produces the next batch of drugs?
b) Production started 6 minutes ago and has not yet finished a batch. What is the probability the production process still won’t be finished 15 minutes from now?
c) The factory now opens two additional production lines. All three lines operate independently and produce at the same rate. What is the probability at least one of lines finishes a batch of drugs in less than 15 minutes?

One Proportion . Nexium is a drug that can be used to reduce the acid produced by the body and heal damage to the esophagus due to acid reflux. Suppose the manufacturer of Nexium claims that more than 94% of patients taking Nexium were healed within 8 weeks. In clinical trials, 213 of 224 patients suffering from acid reflux disease were healed after 8 weeks. Test the manufacturer’s claim at α=0.01 level of significance. State the conclusion. State the null...

A company is research a new drug for cancer treatment. The drug is designed to reduce the size of a tumor. You are asked to test its effectiveness. You proceed to take samples from patients that are trying the drug. For each patient you take two measurements of its tumor, before and after the treatment. You want to see if the tumor's size has decreased. Assume the population distribution is normal and α = 0.05. The results of the samples...
