Chapter 6, Problem 1CR
Terminology Consider the data set consisting of the whole numbers 1, 2, 3, 4, 5. Is this data set discrete or continuous?
Expert Solution & Answer
To determine
Whether the data set consisting of the whole numbers is discrete or continuous.
Answer to Problem 1CR
Solution: The data set consisting of the whole numbers 1, 2, 3, 4, 5 is discrete.
Explanation of Solution
A discrete random variable is the variable that can take on only a finite number of values or a countable number of values. Since, the provided data set is consisting of finite values, thus, the provided data set is discrete.

Since no existing treatment exists, they have planned a one-armstudy. They wish to test whether the success rate of the drug is better than 50%, whichthey have defined as the null success rate. Preliminary testing has estimated the successrate of the drug at 55%. The investigators are eager to get the drug into production andwould like to plan for 9 interim analyses (10 analyzes in total) of the data. Assume thesignificance level is 5% and power is 90%.Besides, draw a combined boundary plot (OBF, POC, and HP)
