Homework Answers
I>the width of k1% linear CI for the Kaplan Meier product limit estimate of s(y) must be greater than the width of the k2% linear CI for the kaplan Meier product limit estimate of s(y)...and along with this lll is also true...hence I and III are true...
So E is the required answer(ans)

15) Which of the following statements are true? I. If a population parameter is known, there is no reason to run a hypothesis test on that population parameter. II. The P -value can be negative or positive depending upon whether the sample statistic is less than or greater than the claimed value of the population parameter in the null hypothesis. III. The P -value is based on a specific test statistic so it must be chosen before an experiment is...
